I must start by saying I am not big into wearing sneakers unless I  am exercising. Have other comfortable shoes that fit the bill for everyday use,and were more fashionable.....until I put these on my feet and didn't take them off for the rest of the day.  The arch support, the cushioning, and lateral support are superior to other performance sneakers I have worn, even better than other Rykas I was replacing. I immediately ordered a 2nd pair in another color. Shoe sizing is a very personal thing. By measurment I have a wide foot but in Rykas must wear a medium because the toe box is roomy and mesh stretches with time
