CHOOSING THE RIGHT FIT
Your choice of ski, boot design and size will always be a very personal and subjective decision. Here we have compiled some factors that should be taken into account when deciding on which ski size to choose.
Optimal ski length is determined according to (in order): weight, physical ability, skier height and type of skier (aggressive/non-aggressive). Less aggressive skiers should choose a smaller size, while more aggressive and experienced skiers may want to choose a size up.
- Measure your height: 175 cm
- Define your skiing level: experienced
- Choose your ski type: piste
- Calculate your required ski length: 175 + Experienced (piste) = 175 + [-5.0] = [170, 175] cm

Why choose the Unisex's ON PISTE Skis SIGNATURE ROC 550 (XPRESS)
POPLAR WOOD CORES provide a good balance of weight, dampness, and elasticity for a versatile blend of power, agility, and playfulness.
Combining deep carving sidecuts with wider, modern waist widths, our OVERSIZE SIDECUT delivers powerful carving precision and edge grip with increased stability and control.
RECTANGULAR SIDEWALL constructions feature a horizontal layering of core materials (wood, fiberglass, metal, etc.) combined with full-length vertical sidewalls to deliver optimized edge grip, precision, balance, and power.
Racing power and precision is now more accessible than ever before. Designed for faster acceleration in-and-out of turns, new FLEX TIP TECHNOLOGY offers the adaptive torsion control at the tip and tail to engage carved turns instantly and release with ease. The unique design efficiently channels energy for cleaner power transfer, resulting in the effortless, spontaneity to roll in and out of carved turns and find your flow.
Based on our patented Line Control Technology, LCT CONSTRUCTION offers fluid stability and control with increased forgiveness and accessibility. The central power rail is integrated between the core and the topsheet to reduce counter-flexing for smooth stability for confident control.
MINICAP construction features a small bevel along the entire topsheet for enhanced durability.
Our new Premium HARDTOP offers uncompromising topsheet durability and graphic richness to protect and prolong the life of your skis.
Designed for on-trail precision, our ON TRAIL ROCKER profile features traditional camber through 95% of the ski length for explosive power, snap and edge grip, with subtle tip rocker (5%) for easier turn initiation and control.
