نعال حرارية

I was worried about finding insoles that actually fit my G-Summit boots, but these dropped right in with zero trimming. The extra warmth is noticeable even on chilly morning starts.

Drop-in fit was flawless for my G-Summit boots, no slippage or bunching even on the steepest sections. My toes stayed noticeably warmer during a cold pre-dawn start, which made a real difference when we hit the glacier.

I was worried about heat loss on my summit attempt, but these insoles fit my mountaineering boots perfectly and kept my feet noticeably warmer during the long, cold belays. The material is denser than standard insoles, which gave me better support on uneven terrain.
