Have had leg and knee pains for over 20 years, knee reconstruction, arthritis etc. I now won't buy anything but ECCO shoes. Bought these to walk Vegas recently. Great style, goes with jeans or dress pants. Leg pain was minimal,but thats a lot of walking! Would have been impossible with Cole Haan's or Nike sneakers. I wear a size 10 - 10 1/2 normally. I wear size 44 in ECCOS.
