The sparkle isn't nearly as good as I'd expect for the price ($30) and I've have THIN soles on my sandals and these are THIN. It feels like your walking on cardboard. Also these are so true to size, if you're a size 8 for instance you can't even see the outline of the sandal around your foot and would most likely get over hang, so go up a half size. Other than that...the part between the toes doesn't feel like it's be terribly uncomfortable.
