Agreed, however I have noticed them glop & wet up, & the Nikwax has virtually stopped this happening, with the added benefit of improving the glide!!
I prefer the Moarrr traction which is good for our ice, boiler plate, "Cairngorm concrete" etc, means I don't have to use the harscheisen quite so much!
Personally I prefer durability & traction, which means a USA nylon as the Europeans use a thinner backing fabric & having skinned over some nasty stone "fins" which would have shredded a euro mohair I'll put up with the less glide!
Ever heard of resistance training?...
