Using a grinder to refresh the edge on climbing shoe soles
|
Hey there--the other day I used a grinder (with a diamond blade on it) to create nice flat edges on some shoes that had started to round over but were not quite ready to re-sole. I was pretty careful to remove as little material in the sole as possible and it seemed to work pretty well. |

I am pretty good at using tiny foot holds and I don't want really sharp edges on my shoes. I usually sand them off new shoes with rough sandpaper or rub them a bit on a stone. Sharp soles just roll off of small edges. It sounds like you need to work on your edging technique. For super micro front pointing I don't want them too rounded, but other than that I find shoes climb the best just before they are worn out. I want to feel the rock. |

Wire brushing the sole helps restore stickiness. |

Climbed today with the shoes and they worked much better than before~I would recommend this for sure. Any tips or thoughts on the best way to refresh the edges of climbing shoes? Anything to be careful about or avoid? Maybe this has been covered before... Thanks!You would be getting yourself a fresh, large fish, do the chopping of the fishhead off of the body, and then you would be rubbing bloody side viciously against the soles. You wait for dry, and send. |

It sounds like you need to work on your edging technique.I've heard that from a few people who prefer slightly rounded sole & I'm sure that's the way they like it & they climb plenty hard. But to categorically claim that sharp sole rolls off small edges and that if you prefer it that way you don't know how to edge, well, that's just arrogantly presumptuous. |

I should have elaborated how if you find sharp edges helping, it is usually a case of not using you foot and body positioning as well as you could. If you were using a very hard soled boot, then maybe a sharp edged sole would help on little edges, otherwise, too sharp an edge doesn't have enough support and deforms. |

C4 tends to deform (esp in heat) so a sharp edge was never really good. CWorn down C4 soles were always the best edgers. With the newer Vibram XS Edge, specifically made to resist deformation, I've found that a much sharper edge on the rubber is a-ok and works better for me on certain types of edging. Somewhere there's video where TC talks about how many pairs of TC Pros he's gone through and I THINK he talks about needing new, fresh edges... Could be totally off on that though... |

Thanks for all of the replies. The shoes do have Vibram XS edges~so maybe there is something to that. |

I used to race formula cars a long time ago. There was a chemical you could apply to the tire, then file off the outer layer to make them stickier. I can't seem to find the name or remember where I bought it, though |

Probably wouldn't work for a number of reasons (different optimal rubber temps, different compounds, etc.) Might be an interesting experiment though. |

Have managed to use a hand file over the years to grind to what I need,,and some pure chemical acetone for making it sticky once again. |

I'm interested in some of the tricks that the top athletes use to get er the most out of their gear. With that, I'm pretty confident that my shoes will always ut climb me. What the other posters have said I will echo, work on you. Body position, strength to weight ratio, and reading the route to find the best holds. I think those fundementals will up the climbing game, but not sanding our shoes. I also prefer when my shoes have been used about 50%. After that break in period, the sensitivity goes way up. |

To be honest, I have found the mods to the shoes have worked out great. I never liked the way they edged and now they work really well for me. While I can respect most everyone's opinion, I'd also say that if you don't like the way your shoes work--try to modify them and see if it helps. |
