I love this shoe. I wear it for tennis- it's very light, makes me feel lots quicker, yet supports my high arch very well and has a non-marking outsole. I've had some knee issues, and this shoe (along with my physical therapy) seems to have helped. I often wear a 10 1/2 - 11 in a
Nike; I ordered this in a 41 and it fits perfectly. I like it so well I'm now trying the Biom running shoe. Friends have commented Eccos are often too narrow for their feet and this does not seem to follow that typical
Ecco style. It is a really comfortable, amazing shoe.
