The pair my 6 year old wore last year had been through 3 kids. Cant sneak around in these! I can afford to keep buying the shoes for them to break only two months into me wearing them. I did not test out the water-proof functionality. They really bother my ears or press against my glasses. The foot measurements they state are spot on. I decided to order size 7 for these flip flops. To top it all off, its a third of the price of almost all the racks on Amazon and made in the USA. Its my second pair of hands, and works to air dry my clothes perfectly. Sadly, my ten year old Teva?s Bit the Dust, so the search was on for a new pair.
