I wore Keen for several years but got tired of paying $120 for them, then I switched to Teva and I liked them except for the very sharp edge at the heel that took long time to wear down. These sandals fit great from the start and NO rough edges! I wear them for walking 3-5 miles at a time and right from day 1, they were very good. Tread on bottom so far is also good. If you're wondering about these, I'd give them a try.
