These work!
Size: M (up to size 9)-Beige
I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌

Great toy to play fetch with the dogs.
Color: Black/White, Size: Large
These balls are a great dog toy to play fetch with your dogs. This not the first ball I have gotten for the dogs. Just the right size and weight for medium sized dogs. I have less concerns about them possibly choking on these soccer balls versus tennis balls. So I can leave them out for them to play with. The are easy to inflate using the included pump. My only concern is the durability of the straps as my dogs have almost torn off one the straps of the previous ball I purchased.

Dog parents; buy this now!
Color: Black/White, Size: Medium
A must have for my pup! I have bought this at least 5 times. She eventually pops them and I need a new one. It's an amazing toy that she can thrash and we can play fetch with

Westie LOVES this toy
Color: U.S.A, Size: Medium
My pup (Westie) adores this toy. This is actually our second one. The ball itself is resistant but the straps will be obliterated. Would definitely recommend! Totally worth the price!

Not durable
Color: Black/White, Size: Large
If you have a dog who likes to pop things then this toy isn't it. Within 5 min she had this ball popped. It was made to sound like it was durable for this type of thing but it definitely is not so just be aware. Now if you have a dog who doesn't pop things easy then this would be a good toy
