These are extremely comfortable slippers, but I don't know how well it's going to stand up to standing on my tippy toes. Luckily for me I did years of ballet, so I have a little headstart in this challenge. I get all my strength up and get on the tips of my toes, up and over my arch, stay for as long as possible, then land in a deep plie. I do this over and over again until my poor toes are sore. Let's see how many I can do.
