These sandals are terrible. The cushioning has separated where my heel is and air escapes every time I walk in them. The toe area is WAY too large, I could have gone down to a size 12 and been happy. There's a cavern where my toes are although I don't have a problem with the shoes slipping on me in normal walking. However trying to hike forest trails in them is a recipe for disaster. I tried to steer away from Keens since my last pair had separation on the straps. But these are 10 times worse. I wouldn't feel quite so bad is these were like $10-$15, but these were $50. Stay away!
