These shoes are light as...really light an springy. Good traction and reasonable support, BUT... Inov8 uppers of this model and the X-Talon 190 tear. They rip on the upper toe box seal. Bramble roots, tough heather on fells will destroy these shoes and at £80-£90 you would have to think before purchasing and spending your pennies and decide... are they going to last, are they going to be worth it! For me the fun you get out of the shoe, steering clear of rough fells or trails and choosing your routes for less abusive terrain.... this shoe will give you hours of trail running, hill climbing joy. Great for 10k races.
