His fell apart too. I could only ride my bike for about 3 miles, before getting off the seat to relieve my aching back side. I attempted to approach this book with an open mind. By the sizing chart, I should be using L as it fits me well and I like the size that Ive chosen. Theyre a tiny bit small but still wearable. De plus, elles tiennent bien dans les pieds. I never thought to protect my ears until I was introduced to Self Pro Ear Warmer Muffs. The downside is they are quite hot but they are stiff and and supportive enough to run in practically. Would definitely buy again and recommend to friends and family. Can walk all day in these shoes without feet hurting or aching.
