Just thought I'd make some much needed feetback.
Not everyone on planet earth has a "regular" size shoe size (If we can even say such a thing a regular...). I for example have a size 46-47 depending on the style of shoe (yeah, I know pretty large) and I cannot purchase these funny and cute slippers.
Considering how for any other type of clothing product you take sizes into a account, you do not take large sizes (or small sizes! a lot of people are stuck at the high 30s) into account.
Riot, you had a cool opportunity and you messed up. You've basially eliminated a lot of potential buyers.
Make more sizes please. Both bigger and smaller.
