These flip flops are so great!  The support and durability just can't be beat. I always order a pair for my son, who wears them every single day all summer. The only strange thing is the size 8-8.5 is BARELY larger than my son's old, identical pair which is 7-7.5, like maybe an 1/8 of an inch?  So strange! However, they fit for now, so I'm holding onto them.
