I am fed up with shoes that get hard as a rock when the temps are in the teens and below (as I am a very early morning runner in a cold climate). Anyone know of any shoes that purport to not harden up in cold temps? Even well cushioned soft shoes will harden up excessively in low temps. I am awaiting a pair of Nkke Pegasus Hypershields to try, but any other suggestions (and I am aware of the UK Gear PT-03 winter shoes that make this claim - they weigh 14.4 ounces, so not on the potential list).
