I love these!
- Familiarity: I've put it through the wringer
- Fit: Runs small
- Size Bought: 42
I really didn't think they would be SO comfortable, but they are! I don't have any issues with them getting loose while I'm riding, and they stay tied. I see mentions about them being too narrow, but I have narrow feet and I sized up (I usually wear a 41 and bought a 42). I have always had problems with my feet falling asleep during exercise, but that's not an issue with these.
Overall, I really love them and bought a second pair so I don't have to go without.
Too much info: my foot is 26 cm, insoles usually ~27 cm. I wear a US women's 10.
