New C4 rubber vs older C4 rubber

You're not a certified resoler either? So I could buy rubber from them as a normal consumer?

I received the rubber today. (Fast!) I paid for 2400 square centimeters of 5.5mm RH and received 6000. (No complaints!) I’m not a certified resoler, although I may be certifiable….

How much did you ended up paying? 

Don't forget to post some photos after resoling the shoes (yourself?) And to let us know if the rubber is everything you wished it is . 

I agree that 24 inches x 1m = 6096 sq cm. So you may be right about that. I also bought a 37x37 square of Dotty Tread, which is indeed 37cm by 37cm. I paid $115 for my 80x75cm sheet (6000 sq cm) of 5.5mm RH. I paid $29 for the DT. These prices are consistent with the UP order form. Shipping was additional, of course.

In December, I bought a new (!!!) pair of UPLace from Nomad Ventures in Escondido. It’s the first time I’d seen that shoe. Now I can truthfully say that RH is the best rubber out there. I prefer wider toe boxes in my old age, thanks to five decades of wearing tight shoes and my resulting deformed toes—yet I’ve enjoyed climbing in the UPLace, which isn’t wide. It IS well-made.

I gave it to my friend/resoler and don’t know how to answer your question.

Sweet baby Jesus…that’s what Alf used to do when he did resoles on the road. After he parked his van on your shoes overnight, you’d get back these flat, pancake, clown-shoe abominations. 

From what I've heard, Adidas has across the board ruined most of their rock shoes.

Bit off-topic, but some UK retailers have been quoted as saying Adidas is getting out of the climbing scene entirely.

Makes sense. Big company buys successful small business, fires the employees, sends manufacturing to China, fails to innovate, quality suffers, shuts it down.

Yep. And don't quote me on this, I'm just repeating what I heard from a UK climbing vendor. And I'm not sure who their designer is these days, since Fred Nicole is designing for SoIll now. Also some of the new SoIll models look kinda interesting. The new Street looks like a comfort all-rounder with Vibram rubber. Might be my jam.

I know the the original formula changed, but it was changed a long time ago. I wouldn’t be surprised if Adidas change it again, the original rubber costs 30% more than the rubber Vibram uses. Butura their rubber and didn’t tell people.

In rubber industry the error margin in hardness is +/-5 (I know vibram said 3) so xgrip and edge could have the same hardness. What is interesting is that both rubbers have the same abrasion resistance. I guess that is what they get  for messing with amount of sulfur amount. 

Just coming across this - Butora's rubber is based on Vibram's? Or C4? Because it feels like XS Grip to me.

no they did not. People saying that are a bunch of loud mouth people wearing Make 5.10 great again hats 

I wouldn’t be surprised is Adidas sells 5.10 after loosing all that money. But you never know, Gulden might be one of those guys wearing Make 5.10 great again hats

Yeah seriously, the climbing community is filled with peanut brains. I like the changes to 5.10 personally, although I don't wear their shoes currently-they do fit way better in my heel.
