    Good things come to those who train.

    The Sidi Men’s Hydro GTX Cold-Weather Shoes free you from the rollers during the winter and let you train in the cold. Built around a Gore-Tex bootie, their Norica and Nylon uppers keep cold air out while neoprene cuffs seal out moisture. The Hydro GTX Cold-Weather shoes use light insulation to keep you warm, and because Gore-Tex has come a long way since the '70s, these shoes won’t suffocate your feet and drown them in sweat. Sidi built the Hydro GTX shoes to fit slightly larger than its other shoes so that you can wear thicker socks on your cold-weather rides. Hook-and-loop closures make it easy to adjust your fit, and replaceable heel pads deliver traction at icy stops.

    Made for a thick sock!

    • Familiarity: I've used it several times
    • Fit: Runs large
    • Size Bought: 41.5
    • Height: 5'10"
    • Weight: 145lbs

    I recently picked up a pair of the Hydro shoes from Sidi. It hasn't gotten super cold out yet, but I did have a chance to take them for a few rides during a recent cold spell. First Impression - Well constructed, feels like the MEGA last, generally wide throughout. Initial Fit - BIG! I am a size 8 men's casual shoe and 8.5-9 running shoe and the 41.5 was big on me. After putting on a nice thick pair of wool socks, the shoes fit just fine. A little slip in the heel due to how wide the shoe is. For me, these shoes are going to be primarily a commuter shoe, so the fit works for me.

    Good not great

    • Familiarity: I've used it several times
    • Fit: Runs large
    • Size Bought: 48
    • Height: 6'3"
    • Weight: 230lbs

    These boots definitely run large but that is good so one can add an insulated insole and wear thicker socks. I ordered a 48 which is my size in the other 3 pair of Sidis I own. I've worn them on half a dozen rides in varying temps. They kept my feet realatively warm in 50 degrees and allowed me to ride 5 more miles than the Louis Garneaus that these replaced in 40 degrees. There isn't much insulation and I will stick to my Lakes when it is less than 40. I bought them on sale and will gladly wear them above 40 degrees. They are comfortable just not warm

    Nice Quality. Just Not for Narrow Feet

    • Familiarity: I returned this product before using it
    • Fit: True to size
    • Size Bought: 44
    • Height: 5'11"
    • Weight: 180lbs

    Sidi always does a nice job. Got them for a good sale price. Not sure they're worth the retail price though. These would have been better with an adjustable heel and caliper buckles like my Ergo 2s. I used extra inner soles and thick Smart Wool socks, but still couldn't keep my heel from moving around, up and down. So back they went. I am perfect a 43.5. These only come in whole sizes so I got the 44. They are true to size, just not good for narrow feet.

    Great warmth. Run a size large

    • Fit: Runs large
    • Size Bought: 48
    • Height: 6'3"
    • Weight: 200lbs

    Keeps warm without shoe covers up to about 25F. I wear 2 pairs of wool ski socks since they run one size large, but this keeps my warm so it works great.

    Warm but not waterproof.

    Have used these several times in 35-40 degrees and they work fine. Have used them twice in rain—after 1.5 hours of light rain my feet were wet, despite waterproof booties over them. Not sure where the water got in, but I suspect that you need to wear something like a gator to keep water from getting in at the top of the boot.

    Does what I had hoped it would do!

    • Familiarity: I've used it several times
    • Fit: Runs large

    To rid myself of booties and just hop on the bike in the winter is what I was hoping for. No booties' edges catching on my cleat, no struggle to get them on, no cramming extra socks into my summer road shoe and no cold toes. Used them in temps down to 30 with just a mid weight wool sock, added a thin liner sock under the wool for the cooler days. Comfy toes for good two hour plus rides. Even when temps heated up on longer rides into the 40's, did not get hot or wet feet. They are just about perfect for winter riding. I normally wear Sidi Mega 44.5 or 45 depending on the model, so these 45's had a slight bit more room, which was great on the double sock days. The sole is nice and stiff and the shoe is very comfortable right out of the box. I have not used them below 21 degrees yet, but imagine a thick wool sock and liner will be all that is required to have happy feet.

    Warm at last.....

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs large
    • Size Bought: 46 vs. 45 normal Sidi summer
    • Height: 6'2"
    • Weight: 195lbs

    My feet get super cold in a hurry, something I attribute to frostbite decades ago. With the recent drop in price, I took a flyer. I wear a 45 Sidi normally and in these I got a 46. I tossed the insole and replaced it with an Aerolight insole. I have been out on two 40ish mile rides since the change. One was damp, overcast and 34 average the other was 28 and sunny. In both cases my feet were warm and comfortable with a mid-weight merino sock.

    I do not care about water resistance, but can see the obvious issue at the top of all boots while riding.

    Not what I was hoping for

    I am glad I got these on sale. Had I paid full price I would have been really disappointed.
    I've been riding in these for a week. Every day during my commute. I bought them a little large so I could wear extra socks with them.
    Some other people in my club then commented on FB that these are not water proof. Even though they are Gortex. Oddly enough I haven't had the opportunity to find that out (in Seattle, no less)
    Friday morning was 27 degrees out. I wore two pairs of socks and my toes still got cold. Not painfully cold, but I could tell they were getting cold.
    So, they supposed to be waterproof but reportedly they aren't. And even though they are insulated, they aren't as warm as I though they would be. Others I know who own them claim you have to wear a booty over them. I do that with my normal bike shoes. I figured these would alleviate that issue. Guess not.

    If I could do it over I would skip them all together. Definitely wouldn't pay full price for them.

    Typical Sidi Quality

    • Familiarity: I returned this product before using it

    These do run slightly large (size 47) however they fit more narrow than their road shoes (Genius 6.6 and Wire). This is most likely due to less stretch in the heavier shoe material. Regretfully I had to return them due to the narrow fit issue. Otherwise they are a really well built and designed shoe.

    Sidi Hydro

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 46
    • Height: 6'1"
    • Weight: 195lbs

    I commute daily with a round trip of 40 miles here in the PNW. I got these to replace my other summer/fall sidi shoes and man I'm glad I did. In mild conditions 35 degrees upward my feet stay warm and dry below 35 my toes get cold, but considering my other shoe alternatives these are a great product. My feet stay dry and I've seen other reviews that challenge this and I suspect are overly critical on the product. I wonder if the water is not running down into the top of the boot instead of around the straps etc - if thats the case no foot wear I am aware of will stop that - not even my fly fishing boots. To date my feet have not gotten wet yet while wearing these and I have ridden through some junk weather down pours up pours etc. The shoe fits a little lose as I suspect they assume you'll be wearing think wool socks although I don't it's nice that it accommodates them if I do decide to do that. The soles are stiff very stiff - very awesome. If I needed a pair of these I wouldn't hesitate especially at the current price point. One last thing I'll say is that I've used Sidi products for over 20 years across cycling and motorcycling to include road racing. Sidi makes a great product and the shoes wear and last very well. In fact I've had shoes and boots, although they may not smell the greatest, last over 10 years.

    Nice cold weather shoe

    • Familiarity: I've used it several times

    I bought the same size as my specialized road shoe (45), it most definitely has more room than my normal shoe. It feels a little big but workable with normal socks. It is not as comfortable as I'm use to, but in fairness they are the second pair of cycling shoes I've ever owned. I bought them because they are waterproof and warmer. I've worn them on one ride so far, definitely warmer. I've already decided to get a better footbed for comfort. They were ok in the lower 50s with thin wool socks. I suspect they could work out at much lower temps with the right sock.

    UPDATE: I've used these shoes quite a bit more now. They have "broken in" and become more comfortable even though I haven't replaced the foot beds. I've been down into the very low 40s wearing a thin sock with no comfort issues there. They're expensive but well worth it to not have to deal with shoe covers constantly.

    Very nice but very pricey

    • Familiarity: I've used it several times

    This is basically a very nice mid-level summer shoe with a Gore-Tex lightly insulated body and upper. Nylon sole, standard straps. Call it a $180 shoe with a goretex and insulation upgrade, which do not in my view justify a $150 price increase, although there are not many decent winter road shoes on the market so these could be the best alternative if you do not want summer shoes and heavy booties.

    Pros - fit is right-on for Sidi and despite the non-carbon sole has a very nice road feel. Straps allow easy on-bike adjustment with heavy gloves. Fairly warm but not winter-warm for most folks. Top neoprene ankle band does seal pretty tight and well.

    Con - price and not nearly insulated enough to be a true winter shoe.

    Fit - Has a bit more volume than same size Sidi road shoe, BUT has a very thin cheap insole so if you replace that with a supportive insole you have less room for thick socks. I am very comfortable in my Ergo 41's and got these in a 42 and am glad I did - I think most people will need to upgrade a size if they will wear heavy socks and/or insole replacement.

    Bottom line - great $250 shoe that retails for $330.

    That sizing info was exactly what I was looking for. My regular SIDI road shoes are too small for the thickness of socks I normally wear. From comments I've read about these shoes and their "extra room", I figured I should buy the same size in these but I think I'm going to go up 1
