The Nitro Fate TLS Women's Boots pair a dual-zone speed-lacing system with a mid-stiff flex built to grow with a rider moving from intermediate turns into advanced terrain. Two independently tightening zones and low-abrasion Dyneema laces lock down a precise fit in seconds, so more of the day goes toward groomers, powder, and park laps instead of retying laces. What Our Gearhead® Experts Are Saying:"My heel used to lift by the third run until I found the Re/Lace Liner Locker, the liner's own lace handle that retightens fit without touching the boot's shell laces. I pull it once at the lift and again after lunch, and my heel stays locked the whole day."
