Don't be fooled by their odd looks! Like all RBH VaprThrm® products the Hi-Rise sock works by blocking evaportive heat-loss keeping heat and moisture from moving into the insulation of the 200 weight Polartec fleece as well as the inner boot. The technology has seen a decade of use in the coldest and highest places on earth.
After repeated requests for custom calf length Insulated Socks we now offer this version which stands 15.5" (a full 4.5" taller than the original). The sole shape is exactly the same for this version as it is for our Vapor Barrier Liner and Insulated Socks. However, the volume in the foot and ankle has been reduced to eliminate folds and pressure points to accomodate lower-volume footwear. This is the ideal sock for telemark boots, snowboarding boots as well as trimmer mountaineering boots. Calf measurements range from 14.5" for size 5 and 16.5" for size 11 with aprox 0.33" increment between sizes. The material does stretch as well, but if your calf falls way out of range you will want to order a custom calf circumference either to eliminate extra folds of fabric or to avoid constricting circulation. Please refer to the sizing chart below. If you do not fall within our standard sizing, include your measurements for custom-made socks. Additional $8 charge for custom-sized sole. Additional $8 for customized calf.
The fabric is our patented VaprThrm® insulation with lightweight, soft polyester wicking lining, vapor barrier film and Polartec 200 fleece. Product and materials made in USA. Machine Washable. Color of sock may vary depending on availability of fabric..
These socks are not recommended to be worn under alpine ski boots.
