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

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 for cold-weather riding
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.

PROS: Keeps You Warm, Easy To Use, Durable, Lightweight, Versatile

BEST USES: Street, Long Rides

Sorta warm feet
Was great at keeping the wind out and cold associated with the wind. But when temps dip down with or without wind my feet were still cold. I really like them and my feet stayed warm at temps above 32.

PROS: Keeps wind out, Warmer than without

CONS: Not for cold temps

Used once on a commute with the temperature in the mid 30's. I couldn't tell a difference versus using regular socks. These are a bit tight with high arches.

PROS: Versatile, Durable, Lightweight
