Great shoe, poor longevity.
Lovely shoe to run in on technical trails and rocky fell routes. Not so good when slippery underfoot, but this isn't what the shoe is meant for as the sole isn't that aggresive. Fine on short stints of tarmac, but off road is where the shoe shines. However, I've had a couple of pairs of these and have had no more then 300-400 km of running from them before the upper has worn through; in the shoe's defense I work them incredibly hard and they are light, so I guess something has to give. If it wasn't for this I would award 5 stars.Low to the ground, light,responsive, and offering s-lab tech without an s-lab price, these are a great trail shoe, but save them for Sunday best.
