Each individual alpaca fiber is semi hollow and acts as an all natural insulator to trap warmth. This is the reason that you can wear very light weight alpaca garments and still be ultra-warm. These boot liners are made from 100% alpaca. They are only 3/8 of an inch thick, but don't be fooled by their size. Just that small layer will make an amazing difference in what your foot will feel like. No one wants a boot insert that is thick; those made with 100% alpaca are perfect - lightweight, warm and cozy - offering excellent protection against the cold while still providing a very comfortable fit inside your boot. Other liners can be bulky and make your boot fit too smugly. These will wick moisture away helping to keep your feet dry and comfortable. They are hypoallergenic, lanolin free and naturally odor resistant. Made in the USA from North American alpaca fiber, these insoles come in three sizes. You can trim them for a perfect fit.
Medium - Ladies 7-10 (10.25 inches long X 4 inches wide)
Large - Men's 10-13 (11.5 inches long X 4.5 inches wide)
Extra Large - men's 13-15 (12.25 inches long X 5 inches wide)
