"What Our Gearhead® Experts Are Saying: ""The Profile Step On TLS is dialed for riders who want speed and performance in one package. The Cloud 9 liner is one of the best on the market, and with TLS plus a BOA ankle strap, I can lock in my fit exactly how I want it. Pair that with Step On and you’re riding in seconds with zero compromise."" We ride the Nitro Profile Step On TLS when we want pro-level comfort and response paired with the convenience of Step On. Designed for intermediate to advanced riders, this boot delivers a medium-stiff flex that’s powerful enough for freeride lines but versatile enough for all-mountain laps and park features. Quick transitions, precise fit, and premium comfort make it a go-to for long days anywhere on the hill. The Cloud 9 liner is developed with Nitro’s top riders for unmatched comfort, heel hold, and support, while the RE/LACE system and ILS liner lacing keep the fit secure. Nitro’s TLS Twin Lacing System with Dyneema® laces makes zonal tightening fast and reliable, and the BOA ankle strap provides micro-adjustable foothold right where we need it. Underfoot, the Ortholite High Cup dual-density footbed cushions impact and provides lasting support, while Therminator Shield insulation keeps feet warm in cold conditions. Finished with a Step On outsole made from recycled rubber, the Profile Step On TLS is built for seamless compatibility, eco-conscious durability, and all-mountain performance."
