With a roomy fit and a palatable price, Diadora's X Trivex Plus II Shoes make a worthwhile addition to your mountain bike kit. Diadora constructs the shoes' uppers with rugged Suprell Air Mesh, which is a mix of mesh paneling and perforated synthetic fabric that works to keep your feet cool on the trails while retaining its structure to withstand unplanned encounters with the ground. These shoes are also constructed on Diadora's Ride Plus last, with a more forgiving fit in the forefoot than some of its slim, pro level options. When you're grunting over a rocky crux, the last thing you'd want to feel would be power sapping slippage in your shoes. Diadora addresses this by including two hook and loop straps along with a top ratcheting buckle on the X Trivex Plus II, enabling you to fine tune the fit along the top of your foot and make sure it's secure enough for hard pedaling without cutting off circulation in your toes. Underfoot, Diadora's Sport MTB composite reinforced nylon sole shoulders the responsibility for transferring valuable watts from your legs to the pedals to keep you moving. It won't have the uncompromising rigidity of carbon, but you won't find it bending with the slightest push either. The outsole is also lugged, so you'll be able to hop off your bike and navigate treacherous sections of trail quickly without worrying about sliding around.
