Ummm -5 is stretching it, it hasn't hit that cold yet. My grip didn't tear in 5 degrees, so warm temperatures don't matter much. It must be the shoes or something. The only thing that tore up my grip was carpet skating with my motlys on. Any other shoes and no rips at room temperature. You're just unlucky I guess.
And also, where in Toronto are you?
"For those who dont know, AKWD is the illest, multicultural group of snowskaters there is. They thrive off of wet shoes, walking forever, and using axes to destroy enemies and ice. It is a true snowskate alliance, a fellowship."
