The Ghetto Footware System is the
solution for fast, single-day winter routes. Made of feather-light waterproof material, the GFS is compatible with all types of footwear and inner liners. Pair it with your favorite runners, approach shoes, or boots for optimum performance in the wild, or with your loafers for a rainy night on the town.
I've been using the GFS for years on routes in the San Gabriels, Sangre de Christos, and Jemez, and it has always performed well. While the GFS wears out very rapidly (sometimes after only 2-3 trips), a new pair costs only $3.98 and, at least around here, comes with about 4,000 calories of GNS (ghetto nutrition system) energy food. Highly recommended!
