I made them from an old pair of nikki mtb boots spd,cut the toes out cover with mesh then booties,slip a (hand warmer pack) inside before you go wala!! warm feet for hours, plenty of oxygen to keep them activated,the only thing you got to get over os making a hole in you shoe/boot,not something you would do every day,but (necessity in the mother of invention) use a old pair of shoes e-bay them or what ever..and if your a die hard roady?? don't worry, the fasion police don't go out in the winter!!!
