The Clymb currently have Inov-8 Trailrocs on sale at $64.98 for all three models. I use the 255s, for 50-100km runs, but I know the 235s and 245s are the more popular choices here.
They seem to have a pretty good range of sizes at the moment.
I know invites are frowned on by some here, but The Clymb have changed their terms at the moment, so that if you take up an invite both of us get $15 credit. It's not a bad deal, on a popular model, that I haven't seen on before.
