these flip flops are not that comfortable and your foot slips on the soft surface sole; the straps are not tight enough to hold to your foot, so you often find your heel partially on partially off the flip flop.  Keen makes a lot of good shoes and hiking boots, but these aren't it.  I tried to return to amazon, but three weeks is apprently too long for foot wear.  I do not recommend these.

shipping was of course quick and transaction easy with amazon, but wish I could have returned them.
