I wear a 9.5 sneaker, should I order a L, 10-11?
MARCUS H I agree with MM. I wear 9.5. I have used this product. The Medium is snug but not uncomfortable and loose is not OK. As he says, as long as your foot is not too wide.
M M IMO, you should go down a size. Loose neoprene will rub and may blister your feet. Tight is better as long your foot is not too wide
LAUREN F I found the sizes to match shoe size well- L should work for you
Marilyn S Yes, i would recommend a L.
