I be about to order my third pair , but fair warn these be for light duty use . they have soft grippy sole with air pocket that can handle almost anything with comfort on a occasional basis , but be best use if the majority of walking be do in a carpeted area . if you walk on concrete\/tar a lot , you 'll probably find the sole do not last long enough for you taste . first the center air bubble will pop , then the inner sole will crack along the back of the bubble , and once that happen , they leak . Mine have last about a year and a half on average , but I be fairly sedentary most day . definitely not a shoe for foot-dragger .
