Yaktrax Ice Walkers

You put these babies over your shoes or boots and walk with confidence where previously you dared not go.

Flexible, since they're basically tricked-out rubber bands.

They go on and off in a flash, and you stuff 'em in your purse or pocket when you're not using them.

In small, medium and large, to fit anything from a woman's size 6 to a man's size 14.

$19.95 here.

If you want the Lexus version, the Yaktrax Pro (below),

for $27.95, adds a Velcro "performance strip for additional stability and security in the toughest of conditions."
