In reply to Tom Briggs: Everyone makes a dog - Hoka Challengers 2 and 3 fell to pieces very quickly, I had a pair that had holes in the upper after a 100 miles before some lugs on the outer sole fell off. The mids lasted ages tho'.
I've had 2 Ribelle Runs for a year or so now, and the upper on those is really good, ditto the mid but the outsole went a few months ago.
Don't mention Altra Or some Inov8's apparently
