I normally buy the traditional MUSH and I LOVE them! I got these in hopes that they would be just as comfy but a little dressier. They are a bit smaller overall and I haven't been able to wear them yet because I'm 9 months pregnant and my feet are always somewhat swollen... That being said, I want to make it clear that even if my feet were not swollen, these would still be smaller than the traditional, flat MUSH flip flops. They are shorter, narrower, and not as deep (because of the heel). I wear an 8 in the flat MUSH and I would definitely prefer a 9 in these
