Hi There...

I bought some trekking poles at your Oregon store last year. I bought the round rubber tips at the time. I want to use the Lekki asphalt or fitness (L-shaped) rubber tips. However, I read somewhere that i'm not supposed to do use them with trekking poles?  I'm walking pretty much exclusively on residential and business sidewalks and pavement.  I thought the L-shape would give me some good push off.  What would you recommend? Do you know about this topic?  Thanks.
