Update: got a new pair back from Sportiva. No suggestion as to why they should have started to fall apart so early but we'll see how this pair goes.

But....I've discovered how to make these shoes better. Rip out the insoles!!! Stupid daft cushioned "fithotic" insoles!! Much better without them. Did 90 mins at decent pace yesterday with some nice climbs and steep descents and I could "feel the hill" much better.

I might get used to these shoes yet!!
