Lightweight Reliable Protection

Make the mountain your home-away-from-home with the shoe sure to keep you wanting more. The Frost Gore-Tex 2 Mountain Biking Shoe from Sidi has everything you need to make your trail adventures that much more unforgettable. With the SR17 representing the ultimate result in terms of stiffness for pedaling and flexion for walking, this pair will last a lifetime and become your ultimate go-to MTB shoe.

The Tecno-3 System is made up of dials along the entire length of the shoe, allowing the upper to shape to your foot for a fully customizable fit. Sidi's famously reliable and replaceable closures are improved by an all-new proprietary Sidi Wire material. This non-binding essential allows for intuitive and effortless on-the-fly adjustments. Featuring the lighter and higher performing MTB SR17 sole, which is made up of nylon with polyurethane inserts to deliver comfort where you need it most. The shape of the sole tread has been specifically designed for the mountain bike, allowing for a good grip, facilitating mud dispersion, and providing the right stability for owning the trail. The central insert with the Sidi logo is non-slip and is practical and useful for all cyclists, especially for the less experienced users. The toe area is more subject to wear, especially when walking, so that is why Sidi allows for this area to be easily serviced and replaced by screws. Both the original and the replacement toe allows you to mount crampons to improve traction on muddy grounds.

The Sidi Frost Gore-Tex 2 Shoe has all the little details that make a huge difference down the road. A reinforced cup stabilizes and supports the heel for increased power transfer with reduced heel slip. This anatomically shaped plastic also provides additional foot protection in the event of a crash.

Sturdy shoe, but couldn't get right size

I was not able to find a size that fit me. My normal cycling shoe is a Bontrager size 44. These 44's were a little too small and the 45's were way too big. I switched to the 45North Ragnaroks and those had the same fit as my Bontragers.

5 stars because they seem like if I could have found the right size they would have met my needs of keeping my feet warm and dry.
