these sandals are cute & comfy!  I'm normally an 8W (wide), but the 8M fits me just fine! I had originally purchased a 9M, but they were way too big for me, so I returned them!  (some times I get a 9M because I have wide feet).  the fastening system is velcro, so it makes it easy-breezy to slip these on, and go!  no buckles! the ball of the foot, (near your toes), is fairly cushiony! --- that's not a word, but hopefully you'll know what I mean! ;)
