My daughter needed shower shoes for college dorm use, and these are perfect for that: all rubber so they dry quickly, grippy bottom and inside, wide enough. After the age of 25, human brains are significantly less neuroplastic. that was significantly too big and looked quite awkward, like it was just an extra 1/2 inch too big for the shoe. Im willing to give Lobkin plenty of time to respond to me, but not only is the quality of the product important, so is the quality of the customer service. charges fast. Do not buy if youre after something to swim with. LOVE THESE, I shouldve bought a size larger though! I let my friend that suggested the expensive ones and she even liked these just as much. So for large shoes youll have to store it sideways, which is rather strange. There were no rough edges or sharp edges on anything i received.
