Solltest du nach so was suchen:
(Winter Witch)
Frostfoot (Su) This ability works like the spider climb spell, but the surfaces the witch climbs must be icy. The witch can move across icy surfaces without penalty and does not need to make Acrobatics checks to run or charge on ice. She can move across regular snow without penalty, and heavy snow only costs her 2 squares of movement instead of 4.
oder das:
(Boreal Bloodline)
Icewalker (Ex): At 3rd level, you gain resist cold 5 and can move across snow and icy surfaces without penalty and without leaving tracks. At 9th level, you gain resist cold 10 and can climb icy surfaces as if using spider climb.
... da wirst du nur mit Klassenfähigkeiten oder Zauber hinkommen. Trait eh nicht und Feat hab ich noch keins entdeckt.
