Flex Rating – 5 (1 Soft - 10 Stiff)

Flex Link Design – A flexible panel at the ankle between the upper and lower shell ensures an even-flexing, responsive boot without bulk.

Cloud 6 Liner – Pre-formed from lightweight Thermacell materials, this liner provides all-over cushioning for maximum impact absorption with a warm, comfortable, and highly flexible all day fit.

ILS Liner Lacing – The ILS system uses a lacing harness to snugly wrap around the liner and secure it in the shell for a precise fit. Engineered ILS laces provide less friction and have a Dyneema® core for added strength.

RE/LACE Liner Locker – From the innovators at Nitro R&D comes the RE/LACE liner locker, providing easy adjustment of your inner boot lacing without having to untie your boot.

TLS 5 Twin Lacing System – Easy lace engagement and release combined with the low abrasion of Dyneema laces are key features of this highly reliable zonal lacing system. TLS 5 is also compact and low weight while maintaining the proven reliability of thousands of days on the mountain. If needed, servicing and replacing parts is easier than any other system on the market.

Molded TLS Lace Handles – Molded TLS Lace handles provide better grip and comfort for more lacing power.

45˚ Laceglider – This precision-molded low friction plastic insert is positioned at 45˚ in the ankle area, reducing lace friction and making it even easier to tie up your laces.

Bail Out System – Designed to make unlacing the TLS system even easier. This pull tab placed in the middle of the TLS lacing system on the outside of the boot allows for effortless unlacing and record breaking speeds for taking your boots off.

Solo Density Ortholite® Footbed – Provides the dampening and support needed for all day riding.

EVA Midsole – Used on all boots with rubber outsoles, the EVA midsole reduces the overall weight and provides cushioning and thermal insulation.

Rubber Outsole – Nitro combines a highly effective traction pattern with an abrasion resistant high-grip rubber compound for sole durability and bite no matter if you're hiking up the park or down for some snacks.
