Unisex VIONIC FLIP FLOPS Womans size 11/12 or Mens 9/10-(read description- size)

Vionic Flip Flops have Vionic technology that is biomechanically designed to hug your arches and support your feet in comfort, they have built in orthotic which is shown to be effective in helping to treat heal pain(plantar fasciitis). Flexible midsole that absorbs shock, reducing stress on feet, ankles and knees. Great comfortable walking flip-flop. These are in great shape see pictures. These measure 11 inches, no sizing on these but I feel they will fit a woman size 11 or 12 or even a man's size 9 or 10-, again measure your foot or your other sandals- these are 11 inches on bottom at longest points.
