My friend is getting these and doesnt know what size to get. I am thinking large or Xl. He tried on my xl sphynx and they were pretty big. He wears 9 sometimes 10 shoes. Do you think large or medium?

How old is he? If he is still growing he should get an XL because he is border line between an XL and a Large.

I'd say large. I wear a 10.5-11 depending and the XL's were a bit too big.

he is 21 so he should be cool. Ok thanks sounds like the large should work then.
