The Forty Below® Overflow™  supergaiter is a unique glue-on style insulated gaiter for maximum insulation in cold environments, and protection from river ice water “overflow”.  This supergaiter must be glued permanently on to a bike shoe, cross country ski boot, or mountaineering boot.  The design and components are focused for the application to help insulate these types of footwear in extreme cold temperatures, while also helping provide protection to keep water out of the boot area in case of an interaction with overflow water.

Attachment to the boot must be done by the user, permanently, gluing them to the boot. This is typically done using Barge Brand rubber sole cement, or other glue that is designed for attaching rubber soles to shoes such as contact cement for rubber and plastics. 

We have been helping make and modify our boot covers for riders for over 20 years, primarily in a custom mode.  The Forty Below Overflow Supergaiter is now the result of those experiences and input from users.  We really appreciate the interest and look forward to helping folks keep those toes nice and warm! These have been in use from riders and racers in Alaska and other cold places, users who have been able to have happy toes while riding and using them in -30 to-40F.    Please contact us if you have any specific questions.  Happy Riding!

Custom made in CANADA!
