So buy them, you won?t be disappointed. I was going to return them and purchase a wider width, but discovered that a wider width was almost double the cost. They do as good a job if not better, than the much higher product I?m an US 8. Its almost 10 pm now, Ive been rocking music non stop on them all day. Just be sure to use thecorded/cordless drill for putting in the screws to make assembly completely easy. However even though it is loose my foot doesn?t slip out. The soft rubbery material of which the shoes are constructed will fill up with stones that get stuck in them. Battery life seems fine. It seems to be a design flaw as many of them have come off since.
