We've owned other Kamik shoes, both winter boots and sport sandals and have never had any issues with them. We are an extremely active family and our kids put a lot of wear and miles on their shoes. We use these sport sandals for everything from hiking, rainy weather tennis shoes, surfing on rocky/coral areas or just their quick shoes for getting out on their bikes, scooters, unicycles etc.... We live in Hawaii and so these shoes are used year round. They've held up fantastically. Our kids have never gotten blisters from them (which I can't say about other competitive brands we've tried in the past), even on our six mile or more hikes.  Kamik has been our go to brand for some years now and they've yet to let us down.
