I bought this sandal because I have a bunion on one foot and pain across the top of the other foot and no matter how I laced my shoes and retied them before heading back down a trail I was in pain before long and have had to walk backwards down a trail... no funny and in tears. I finally wore my new Teva sandals on two hike! First  hike consisted of a loose rock service road, dirt path and smooth rock up hill as well as water cover rocks to view site and back down to the car.  A given was the dirt stuck to the sun screen on my feet and I got at times little pebbles between foot and sandal, but the sandal did not slide on the smooth rock or fine dirt on the  path and my feet did not hurt but,  were my bunion is I wore a blister in a small spot, didn't realize until I got home .Today was a longer hike, 6 hrs and steeper with sharp rocks.  I place a band aid over my bunion and enjoyed the hike!
