Not comfortable at all. The right shoe is ok but they are very heavy. The left shoe has something sharp on the inside. The stitching maybe. I had to put a piece of fabric and duct tape over it to be able to wear it. Very disappointing for the price. Don’t recommend. UPDATE: I returned the original pair as defective and was offered a new pair. Thought I would give them another try. There was obviously something wrong with the first ones as the second pair is great. Still a bit heavy but can get used to that. Very comfortable as expected! I DO recommend these Flip flops!
