Stiff is a board, light as a feather.
Hammering up steep climbs may not be a favorite past time of every mountain biker out there, but there are some of us who live for them. There is a certain frustration that even the climb-loving riders encounter, and it stems from soft and flexible shoes giving out when you're dancing on your toes to power up through a steep and bouldery section of trail, causing a total collapse of power that has you spinning backwards to try to catch yourself. Fortunately, Sidi has a knack for getting us covered with stiff soles, and the Sidi Trace Cycling Shoe doesn't fall short of that, with the new MTB RS17 sole that increases stiffness without adding weight to the mix, so you can hammer out the climbs, and push to the podium on race day without flex and give that leaves you feeling squirly on the pedals.
The new MTB RS17 sole is lighter than previous SIDI MTB Soles, with a stiff nylon construction that features targeted polyurethane inserts to elevate stiffness. The sole shape is tapered specifically for mountain biking, with a little extra width in the forefoot, and assorted lugs for reliable grip when you're on foot. The toe area uses a replaceable tread, since it's the area most prone to wear and tear, and also features the ability to mount crampons, so you can elevate your grip when you hit the local cyclocross race and encounter more than just a smattering of mud.
Wrapping your foot up snugly on top is Sidi's Politex material —a burly fabric constructed by overlapping several layers of different materials, harnessing their strengths into one piece, and compacting PVC to the layers for a smooth, long lasting finish. Politex is film dyed, ensuring longer lasting color that won't fade after a summer in the sun, so your kicks stay as fresh as the day you bought them. Politex fabric is designed to resist laceration, ripping, stretching, and fading, and even hits the marks for European Green Standards, ensuring that the product is totally green, and less harmful to the environment where we spin our legs.
Topping it all off, your feet will stay secure thanks to the two hook-and-loop straps that secure your toe and arch, plus a reliable Tecno-3 buckle up top that cinches down millimeter by millimeter to dial in the perfect fit for you. The Tecno-3 system involves two ratcheting dials, Sidi's proprietary, non-stretch wire, and a customizable fit at the instep and forefoot.The heel locks your ankle into place, too, with its Tallone Sidi heel cup, that reinforces the area with protection from trail debris, and prevents deformation from extreme riding or prolonged pressure.
