These slippers are amazing! They're comfy, are well made, and are crazy cute. I usually wear anywhere from a 5.5 to 6 in shoes and the 6 fits well, so err on the side of larger if you're in-between. My nephew saw them and said they had to be mine, cuz they're badass like me. The kiddo speaks the truth: These slippers are totally badass! Thanks T.U.K.!
