Comments about Neosport by Henderson Neo-Sport 5 mm XSPAN Sock:

Heed warnings about sizes.7 1/2D mens=M max but perfect. 8=L for sureTop tight going over my heel. Good thing is they will not parachute if worn without pants.They feel great. 5mm feels thin because rubber so good. Thin piping at top pulled tight and round great rubber makes them seem thin, they are 5mm.The seams are strong and well placed.Bottoms not for long distance walking but well worth the money. Heck get two pair and wear them out if need be, [$]! They are great for full foot fins with or without pants. Can't go wrong. The sizes given by other reviews are correct. The rubber is absolutely fantastic, it clings to the skin, they roll on and off. Super.

Very soft stretchy rubber, well made and positioned seams.
Top narrow, must wear under pant cuff
BUT would seal well on leg if no suit worn.
The top won't parachute water.
I feel they are full 5mm as compared to my other two pair of booties. Stiching not piping at top makes them seem thinner.
Great for full foot fins that may be a bit loose. Seal well.
The other reviews are right on as to sizes.
Mens 7 1/2D=M 8=L

I purchased a pair of these for my son. He has a small foot, was unable to find boots to fit. After using these with a full foot fin I may not upgrade to a boot, he likes the way they fit and function.

A nice pair of thin wool socks under creates alot of warmth for cold water diving.they run small, so try to get 1 or 2 sizes larger. Great product..

I am an USA size 11 shoe/boot and the 2XL are the correct size. So they run small. I intend to use these with Cressi Gara Pro full foot fins. The look well built. Seams look good. Bottom has nice, no-slip texture.
