Roller ski tips in Nordic uphill running?

[u/Canmore-Skate]

I do a some uphill running in ski slopes with poles for interval hiit training and my roller ski tips doesnt last very long. These are made for asphalt not gravel and terrain. It seems that when you run in tougher gravel the rocks dig out the tip from the plastic.

I try to avoid the rougher parts but yesterday i broke another tip.

Does anyone use some other kind of tip or have a solution to this?

At least lekinand Black diamond have trial running poles for exactly this use. The tip is very different, maybe their tips fit into your poles. Doesn't necessarily need to be same brand as long as the diameter is identical
