I read fatboybiking blog today comment on cold feet in this sleety weather.
My new idea for morning bed warm feet, as yet untried, is to wear an old pair of XC ski boots. They are waterproof and lightly insulated. I'm relying on the fact that they were designed for active use to prevent my feet from becoming pools of sweat.
The toe bar in front and other accouterments might look a little geeky, but, one fat boy biker to another, it won't be the bottle-neck of our cool. If you know what I mean.
Please note the rental boot numbers and love the magenta trim. Very 1980's meets thrift-store modernity ala Michael Jordan #23. I also have another pair of old three-pin boots that I might try. Less insulation, less color, less hang-time. I may trim the toe off.
