It catches on the ground/floor. I can look past the buggy software issues and the strange on off button (that only sometimes works) but for a newly released set of $150 headphones to not work while charging, is insane to me. My daughter has been dancing for 12 years and always worn Bloch and the real thing has about 1/4" heel, and these are lucky to have a "rubber sticker" for a heel. This is my second pair and they are the best flip flops I have ever had. Serves its purpose, which is to identify my AirPods from my partners. There is no tea tree or minty smell. I dont think anyone but me actually gets the reply because its one of those email addresses that doesnt get replies. These kept my feet cozy without going too far. I dont very many reviews, but I love these headsets so much that I purchased a second set. The trackpad makes the iPad function like a laptop and the keyboard is great, even on the 11?!
