That is not an issue here. Definitely recommend this product. Overall cute slippers! Ive not had such a thrilling experience in many years on modern platforms, and its tight, gripping combat had me on the edge of the seat the entire time. He loved these, so I wore them a few times taking the dog out. The wire channel is cut into sharp corners and goes down against your ear, so it will eventually scrape your skin raw after prolonged usage, like a plastic razor blade. Another reviewer said they opening was too small/tight, but I dont feel that at all. Great price as well for a razer product, and a good size. They have a rubber tag the same color as the strap attached to the heel. I love the imprinted "Ugg Austrailia" logo on the heel.
