The SD15 is a great mixture between MTB and Outdoor shoe. Because of its Outdoor outsole, the SD15 is perfect for routes where "normal" cycling shoes would be unexpedient, and due to the mesh upper your feet are always well temperated.
It features the replaceable Tecno-3 system, with securing Velcro® strap in the forefoot, a functional pull tab on the heel for easy on and off, and the Outdoor outsole witch is also compatible with the SPD click-system due to the 4-hole SPD-plate for cleats.
Tecno-3 System: SIDI's Tecno-3 dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit. SIDI's famously reliable and replaceable closures are improved by a proprietary SIDI Wire material that is completely non-binding for intuitive and effortless on-the-fly adjustments. Like most SIDI small parts, the Tecno-3 Buckle is serviceable and replaceable.
The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure.
Outdoor Sole: The sturdy and strong profiled "Outdoor Sole" is made for difficult terrain when you have to walk from time to time and delivers a good walking comfort. It also offers a 4-hole SPD-plate for cleats.
Please note: Sidi shoes are quite small. Sidi strongly recommend to take one size larger than usual.
