Cross Country Ski Summer Training?

Question

i have been training for cross country skiing for quite some time now, and i have just been running/ Strength training. I recently bought a pair of roller blades and was wondering if i could just use my cross country ski poles with my roller blades and if so what should i put on the bottom of my poles to stop the metal spike from breaking on the pavement.

Note: i do not want to purchase roller skis, i do not like them.

Answer 1

I would just wrap the tips with duct tape.  Its cheap and can be easily replaced when it wears off.
