Northwave have produced an excellent shoe here in the Extreme range. These 2013 versions are very nice, the shoes are some of the lightest available to buy in both MTB and road. Northwave have put a lot of effort into producing these shoes and from what Northwave say I think these shoes would be a very good choice. The sole on the road shoe comes in at 69g which is impressively light. The upper was designed to fit all shapes of feet using BIOMAP design system by Northwave which studied the natural mechanics of foot motion. The sole has been designed around their AirFlow system for good ventilation and the list of top range features continues with the lace system… Awesome shoes from a brand that deserves a little more recognition for creating great products.
