Great Eastern EntertainmentMen's Casual Slipper, Red, 4-10

I love these, so nice to wear around the house and pretend ur sonic lol. Theres a little elastic band inside that makes sure it wont slip either. Though i will say maybe they should make them thicker at the bottom for running better or like include memory foam for support inside the soles. So many ways to improve an already great product <3

Worked great for my sonic cosplay a few years ago!

Perfect

It's good. It has a strap inside and it's very comfortable. I wear a size 9.5 in women and it fix exact on my foot. Easy to put on, great fit for women or teen age boys

My son loves his shoes ! Very comfortable and good quality

I got these Sonic the Hedgehog plush cosplay slippers for my son, who is a big fan of the Sonic movies, and they've been a huge hit. The fit is perfect, and they've truly made him feel super, just like his favorite speedy character. The slippers are not only fun with their vibrant Sonic-themed design but also comfortable, making them ideal for indoor adventures. They're a wonderful blend of playfulness and practicality, perfect for any young Sonic enthusiast.

Fits perfectly fine! I’m a mens 7-7.5 and a womens 8.5-9 and I had absolutely no problem wearing these shoes. They didn’t feel too loose or tight or anything and there’s a Velcro strap at the ankle that you can fiddle with a little to try to make it fit better if you really need it.The shoes are super soft and cushion-y on the inside I wore them for pj day at a pretty movement heavy job and I had no issues and didn’t come home to my feet hurting like usual.All and all perfect addition to my sonic pajama collection.

These can fit a size 13 US male-- my husband tried these on and they fit. There is a velcro piece that allows opening around the ankle. It's affixed to the back of the white "socks" of the shoes. I dont believe these allow any sort of tightening of the shoes but allow for easier insertion of a larger adult foot. There is also an internal red elastic that can be used to go over the top a foot to better secure the foot to the bottom of the shoe or be brought back to the heel to further scoot the foot into the shoe. I did buy these for my 5 year old who wears a size 10 US wide kids. These were way too big for him. He can fit his house slippers in these to allow for a better fit. However, he loves them! He feels like he is Sonic and says he can go super fast! Though, he does shuffle his feet across the ground and risks stumbling over his own feet - though I expected this. If your child loves Sonic, do not hesitate to buy these due to size. They can grow into them and get years of use. I would caution though that since these fit HUGE on a child's foot, be warned that the child can hurt their ankles or fall due to poor fitting. These are also a soft material, like a slipper, and would easily get soaked if worn outside in wet or damp weather/ground. Either way, I'd buy these again to fulfill my 5 year olds dream to be like Sonic.
