I wear a size 7 street shoe, and a size 36.5 in La Sportiva Nago's. I ordered these in 36.5 and my toes were really scrunched up in the front. I am returning and reordering in a size 37.5 to see if the fit is better. Otherwise, the shoe is very nice, a tiny bit more aggressive than my Nago's, with a solid heel.

I'm a new rock climber but have one foot that's very sensitive and needs to not be too smashed in shoes. Buying a shoe 1-2 sizes small and letting it stretch would kill my feet. I went to my local REI and tried on every single rock shoe there, and the Thunder just fit like a glove with comfort far above and beyond all others but still offering a good snug fit. I tested the top 5 or so out on the wall briefly, and the Thunder was all around the best pick. With a slightly lower price, all day comfort, and minimal stretch, it's a winner!

These shoes look great, but I found the heel to be too high and too stiff. I could tell they were going to rub blisters very quickly. I had hoped they would feel better since their description emphasizes comfort. I went with the La Sportiva Mythos instead and loved them for my 5.7-5.9 climbs in Colorado. They smeared & held edges great and never gave me any discomfort.

i've had these for about a year, and they are extremely comfortable. whether i climb in a gym or out on the rock they do the job very well. i made sure to buy them tight since i know climbing shoes stretch, and after about 5 wears they molded very nicely to my foot.

My Thunders are very comfy. I tried on a few different pairs when I first started climbing and these were able to fit snug without being painful. And even though I scrape them along the rock while flagging my feet out a lot there is minimal scratching to the soles/toes.

Haven't actually got to use them yet. I am a beginner who isn't into crushing my feet because of the problems I have with them. These are feel comfortable yet tight enough to keep your foot in place.
