Probably the most secure place on your person to keep money and valuable papers. Adhesive hook & loop attaches a secret fold-over wallet made of thin nylon to your boot’s inner calf or front gusset. Large enough to hold a bunch of money (or whatever else you don’t want found). For some reason neither thieves nor third world border inspectors check moto-travelers smelly, dirty boots. (?!) Hmmm...at least not Greg’s. Set of two pockets: 3.25"×4.5" and 6.75"×2.75".
