For the price it is a great beginner shoe. I read that it runs large so I ordered a size down but ended up returning it for a larger size. They were pretty tight to begin with but have broken in nicely. I haven't taken them outside yet but they have great grip in the gym.

Got this shoe for cracks at the gym because they hurt so much more than the cracks outside. I think I should have gone a half size bigger. Hoping it breaks in a little more. I usually wear 9.5 street shoe and got the same for this shoe. The hand and baggy hands sizes feel ok in these shoes. Still pretty painful on perfect hands and smaller.

Gym. Sport. Bouldering. Trad. Slab. Vertical. Overhanging. The Remora does it all. Easy to slip on and off. Extra rubber on the toe for toe hooking and, I imagine, great for crack climbing. The friction of the rubber is not the best I've experienced on slab, but, for the versatility of this shoe and its price, I don't know if you can beat it in the slipper category. I wear this shoe every day in the gym. The heel slips a lot with the fit that I chose (gym training fit, in between comfort and performance), but that is inevitable with a slipper. Comfortable enough to wear for an entire gym session. I can't wait to try these for crack climbing.

Street Shoe: size 10.5/11

Remora: size 10.5 (I'd say it's true to your street shoe size if you're looking for a balance between comfort and performance, once broken in, of course. So size either your street shoe size or 1/2 size down. I will probably buy a size 10 pair of these for more performance)

Shark: size 11.5
Five Ten Anasazi Lace-ups: size 11 (use for multi pitch, so definitely a comfort fit)
La Sportiva Solutions: 42.5

For the price, nothing compares. It's short money for the type of shoe you can get. I've previously had a pair of Evolv Addicts that are garbage compared to the Remoras.

I've primarily spent the most time with these shoes at the gym in the sport and bouldering area. These shoes have been the best shoes I've been able to find for crack climbing. But I've also used these for some trad routes and slab routes and they've performed great. They've become my do everything shoes.

Plus the easy on/easy off makes these my go-to shoe at the gym.

To give you an idea of my foot shape, I'd got a slightly wider forefoot and a narrower heel. That is part of why I needed to size up. Most other folks are sizing down about 1/2 to 1 size.

Street Shoe: size 10

Mad Rock Remoras - 10.5 (comfortable amount of toe curl)
Mad Rock Sharks - 10.5 (a big uncomfortable after having on for 5 mins)
TC Pros - 42.5
Katana's- 42.5
Scarpa Origin - 42.5

In terms of comfort to performance ratio, I have never tried on a better shoe. So glad the Madrock rep pointed these out to me when they were first released a couple of years ago. They fit like a sock, and are incredibly versatile. You would be hard pressed to find a better sport climbing shoe in my opinion. The flexible material seems to suck onto any foot shape and maintaine a suction-cup like feel on your heel. (I have never experienced the loose heel feeling with this shoe that I have had with other mocasins) My wife, and my brother are also now wearing this shoe and love it equally. Climbing on this shoe 2-3 times a week, they last me about 14 months before the rubber on the toe wears through (just FYI).. I wear a size 12.5 street shoe, and an 11.5 in the Remoras for a good/snug fit. Great value, unmatched comfort, super versatile, sensitive, and just all around great shoe! So glad I found my perfect rock shoe and I hope Madrock never stops making them!!!

I know, I know... they’re Mad Rock. But this is the best moc I’ve ever used. Took them On a trip to Smith rock last summer and they performed really well. They are great when you need to smear and stay stuck to the walls in the chimneys; when you have anything over a quarter inch edge to smear on, and when you just want to shoe that’s gonna stick to stuff and you’re not getting anything super sloppy with micro edges. Plus, they’re mad comfy. Like, no break in time. It’s like a sock, but with rubber on the bottom. There’s not a whole lot of rubber on the shoe, sustaining on your toes on edgy stuff gets a little painful after a while. That being said, I will buy another pair of these shoes.

The soft rubber and slight downturn makes this shoe great for slabs and gym climbing, my only disappointment was the sloppy heel. This is a great shoe to add to your arsenal, but not the best all-around shoe. I wear a size 9 street shoe and went down a full size to an 8, which is perfect.

Shoe has great sticky rubber and and the slip on makes it great for the gym, highly recommend.

Please do not change this shoe, or it's price. I honestly am not sure if Mad Rock realizes the quality to price ratio they have on this shoe but F***. It does it all, I think, I cannot attest to more than 65 degrees, but don't doubt its performance there either. I have a good job, enough money to buy multiple high end shoes, but wouldn't unless I was pro and getting money to wear them in which case it's a moot point (cuz dat be free). Anyways, these shoes are the best overall shoes I have worn in a long history of climbing shoes. Cracks, check, slabs, check, overhangs, check,indoor, f*** yes. I sized down a full size from redlines and half size from sharks. Redline 11 shark 10.5 remora 10. I can wear them for 2 hrs straight and still get the performance I need. If you can only afford one pair of shoes get these, if you can afford multiple get these. Nuf said.

The Mad Rock Remora is a very comfortable shoe. It has a good toe for smearing and slab climbing. The heel is comfortable and solid. I prefer this shoe for less steep routes when smearing in mandatory. Although I've worn the Remora on all types of routes and it always performs adequately. The shoe runs a little large I recommend sizing down a full size. All in all it’s a great all around shoe that is easy to get on and off. I strongly recommend adding this shoe to your arsenal.

Ever since the mocs got bumped up to $125 I've been searching for a new slipper. I was initially skeptical after a review in California Climber called these "great for narrow feet". I have fat feet and I was worried these would be another evolv addict or la sportiva cobra. Nope, not even close. These are wide and soft. The rubber is great and the slight down-turned big toe gives just enough purchase for little overhanging pockets. The rubber is SOFT, like broken in moc soft. Not at all the planks that the addicts are. I would hate to try and edge and stand on sharp features all day, but for most everything else , these are great.

I went a half size down from my street shoe. This should be good for all day comfort and crack. Full size probably would have been good, if I was bouldering and doing steep stuff only.

The rubber is awesome, I feel super confident on nubs and smedges. The rubber on the heel is pretty thin, my ankle was getting pretty sore after a few sharp heel hooks.

Not sure how long the rubber will last, will do a follow-up review once I get there.

The Remoras are a very versatile shoe. I can use them for more vertical climbs as well as my more overhung projects. This being said while they perform well on both, I prefer them on more vertical terrain because they aren't overly agressive. They feel pretty tight when you first put them on, which is why I only like to downsize by a half size. The heel had more room in it than I would have liked, but it still could perform well. The toe fit me superbly, which is why I think they're such a good fit for more vertical climbs.

I've been sport climbing and crack climbing for 8 years and have tried most of the shoes on the market. I have never been happy with a slipper before. Slippers have in general, felt sloppy, poor fitting and too soft for edging.
The Remora is completely different. It has a more precise, slightly narrower fit than most slippers and delivers a ton of power to the toe. The friction on the rubber is the best I've tried.

I have worn two sizes, one a full size down from my street shoe for bouldering and sport climbing, and the other a half size up from street shoe for crack climbing. When sized appropriately, these shoes are incredible for crack climbing as well. The toe profile is slim enough for thin cracks, and the high-friction rubber grabs rock hard. The extra rubber on the toe adds a bit of toe profile thickness, but the added friction makes up for that.

The Remora is quite comfortable and easy to get on with the pull-tabs.

Overall, this has become my go-to shoe for boulders, sport climbs, and cracks. I use it for everything other than very steep projects with small feet requiring a lot of toe in.
The Remora will not perform as well on really steep rock with tiny feet where a super aggressive shoe can help toe in. For this, I use a more aggressive shoe like the Redline

These shoes are great! The shoe fits like a glove all around your foot. It is a perfect medium between an aggressive downturned shoe and a flat slipper perfect for edging. There is a slight amount of aggressiveness mixed with the perfect flatter sole, making this shoe perfect for any type of climbing from hard boulders to multi pitch slab. It is pretty soft but I normally dislike soft slippers and these have totally changed my mind! The heel fits perfectly to my heel (which I often struggle to find with slip-ons). My favorite part of this shoe is its edging ability. These things can edge on anything and are perfect for smearing and micro-nubs. Also, these shoes have the best rubber I have ever felt. They stuck together out of the box!! and the rubber is extremely durable. The remora's are slightly soft but form sturdily around your foot for the extreme precision. Extremely comfortable even when wearing very sized down. Definitely the best slippers I have ever climbed in and these are now my go-to every day shoes. For sizing, I wear an 11-11.5 street shoe, 9.5 Sharks, and 8.5 Remoras (so size down because they will stretch and run a little large!) 100% recommend

These are the most comfortable climbing shoes I've ever worn even when sized aggressively. The rubber is super soft and insanely sticky. I use them for everything except when I need to do hard heel hooks, something inherently lacking in a slipper. I'm a 9.5 in street shoes, 9 in the sharks, and an 8 in the remoras.

I absolutely love these - and I rarely like slippers. Fits like a glove and is simple yet performs incredibly well. Great for toe hooking and cracks - allows you to edge really well. This is definitely a soft shoe though, so when it comes to crack climbing and trad climbing, they can be really, really good for single pitch, but multi pitch my feet start to hurt. However, I am used to a stiffer shoe, and not all people agree with me. Amazing for sport, bouldering, and gym sessions as well. As with most slippers, size down a couple sizes!!! They do stretch a bit and I noticed that they fit my feet perfectly at first, even a little tight, and got a little too loose after wearing them many times and sweating in them. Great deal. Totally worth every penny, and I would recommend them to anyone from kids to adults, male or female.

Comfort comfort comfort. (pssst. and performance!)

The Remora has everything I would ever hope for in a slipper: soft, slightly aggressive, comfortable, versatile, and they toe hook remarkably!

And quite inexpensive! I own 2 pairs so I have a backup when my first pair wears out!

I wear a 11.5 street shoe and got an 11 in these and it was perfect

After a lifetime of wearing almost exclusively stiff shoes, the Remoras have converted me into a soft shoe believer. They are the first shoes I take out of the bag for anything that doesn't involve heel hooks or ultra-thin edging–weaknesses of any soft slipper. Some of the stickiest rubber I've ever used, as well. During a two-month trip to Rocklands, I used these shoes somewhere around 90 percent of the time.

I wear a size 10 Shark 2.0 (same as my street shoes) and 9.5 Redline, and a size 8.5 in the Remoras. They will feel tight at first, but quickly stretch and mold to your foot shape.

The Remora is probably one of the most comfortable, if not most comfortable shoe I've ever worn. I wear size 9 redline, 8.5 Shark 2.0, and was recommended I wear size 7.5 in the Remora. Skeptical but trusting, I got the tiny size and was amazed when the heel cup stretched back and snapped back once the shoe was on. Definitely stretches, so size a bit small at first! The shoe is a good all around shoe for high millage in the gym or otherwise. Soft rubber, surprisingly good edging, good smearing, and good toe hooks. The shoes main flaw is that my heel often slips out, but hey, it's a slipper.
Full disclosure: I was provided these shoes for free, but did my best to be objective

I've been climbing in the Remoras for about 6 months now and they have easily replaced all of my other shoes. They fit my foot like a glove - there is little to no dead space (which is extremely rare for me). I tend to gravitate towards more stiff shoes, but I actually love how soft the Remoras are.
For reference: I am a 6.5 in the Redlines and a 7 in the Lyra. I ended up going down to a size 5 in the Remora and they've stretched perfectly.
