● FAQ

QUESTIONS FROM
THE BENCH.

The four things players ask us most after they pull a recommendation.

Yes — most players go a half-step shallower for warmer ice (late spring / outdoor) and a half-step deeper for colder mid-winter rinks. The recommender accounts for this once you pick a surface, but be aware that arenas vary even week to week.
