Going to be sending a pair of Katana velcro up to Llanberis for a re-sole, but I'm really not that keen on Vibram's XS Edge rubber.
I've never used 5:10 shoes, so have no personal experience with their different compounds. I can choose between C4 or Onixx
Is anyone able to give me a definitive answer of the difference?
I use them in a totally all-round way. Indoors, sport climbing at Cheddar & Brean and for some slabby boulders
