The Mavic Rush Shoes have many of the features of the top of the line Mavic Fury, but at a price and comfort level that is preferred by many cross-country riders. Not everyone wants to pay for or put up with carbon soles in their cross-country shoes. Cost can be an issue. Why spend big bucks on shoes that will inevitably get trashed in the mud and dirt. Another reason to steer clear of carbon is the stiffness of the sole. While a big plus for transferring 100% of your leg power to the pedals, it can be a drawback when shouldering the bike and hiking up a steep, slippery slope since it doesn’t flex easily. The sole on these Rush Shoes is nylon with glass fiber reinforcement. This allows for flex at the toe so you can hike and climb over rocky ledges without feeling unnatural. At the same time, the area from the cleat to the heel is plenty stiff enough to transmit power to the pedals. Like the Fury Shoes, the Rushs use Mavic’s Contragrip outsole. We’ve worn lots of shoes and it’s the best thing we’ve worn. It’s a sticky durable rubber and is beyond compare when treading technical, rocky terrain. Up front, there is a toe cap that both protects your toes and adds durability to the shoe. The upper has the familiar ratcheting buckle with two Velcro straps, forgoing the more complicated cable-and-Velcro system of the Fury. Inside the shoe is the Ergo Fit 2D insole. It’s a two-density insole with a high-density heel cradle. The insole is covered in an anti-bacterial material that resists stink. The foot is protected at the top of the shoe with a micro vent tongue. It’s perforated for ventilation and lightly padded to give a little cush, but not so much that your foot has room to move around when pulling up. The Mavic Rush Shoes come in sizes 7 – 12. 5 in whole and half sizes. The shoes come with removable toe spikes. There are two color options — Black or White. Weight (for a size 8. 5 shoe) is 375g per shoe.
