Great Price on a good product
Used these under my Sidi Vortice Air on a cool day - feet stayed warm and dry all day long. It was not a bitterly cold day, but without these my feet would have been frozen. The long periods of heat here in Central Texas call for perforated leather, so these all for all year around comfort.

PROS: Easy of use, price

CONS: Material may wear easily

Prior to using them, I didn't think they went far enough up my leg. But, after using them in cold weather - my feet and legs felt very comfortable. I'll never go on a cold ride again with out these liners.

Perfectly Warm!
I ride an hour and a half to work and then again home. On very cold mornings I wear all my Freeze-Out clothing (socks, long johns, shirt, and jacket) and have absolutely NO problem staying warm! The socks I wear over regular socks, inside my sneakers. I do NOT need to wear warm shoes or socks, even in freezing temperatures.

PROS: Very warm, Lightweight

CONS: Difficult To Use

Great liners
These boot liners are excellent. light and small enough to pack and use when needed and they really take the edge off. I also purchased the glove liners and "long-johns" as well as the neck guard. I'm very pleased with all of these. I'm going to try the neck guard and glove liners up skiing.

Great item for cold riding weather
I took a ride with my full Freeze-out gear under my Riding jacket, and these products worked as advertised. By mid-day I was actually getting too warm. The temperature was about 45 degrees at start of ride, and around 58 degrees at noonish. I have the neck warmer, gloves, shirt, long johns, and boots. All of these I would recommend if you like to ride when you want to ride.

What size shoe does a 2xl fit?
A shopper on Dec 28, 2016
