Full Tilt

Whether you're pushing out the gates and queuing up fatty cliffs, or dialing in your comp run at the park (or moguls, we're not here to judge), the Full Tilt Soul Sister Ski Boots are the go-to option for all-mountain destruction. Shred hard thanks to the continuous flex of a 3-piece boot and fully customizable Intuition® liners that'll keep you sendy all day. Throw in a grippy, replaceable rubber outsole for those windswept bootpacks and spicy parking lots, and the Full Tilt Soul Sister Ski Boots are the perfect accompaniment to a life spent on the mountain.

Product Details


Last: 99 mm – The original width shell that your feet love. Ideal for average to narrow width feet.

FTS (Full Tilt Soul) Shell – The FTS Shell takes the same 99 mm last width and geometry used in the original 3-piece design and incorporates a roomier toe box, allowing room for your toes to play.

Easy On/Off – Tongue fully opens like a convertible, never blocking your foot. Slide your foot in and out easily with comfort in all temperatures.


Women's Cuff – Anatomically shaped to match a female's specific calf shape for increased comfort and control.


Flex Rating: 6 (1 soft - 10 stiff) – Maximum versatility & reliability in all conditions with a smooth, natural ankle motion to eliminate shinbang! You can quickly change your flex by swapping out different # flex tongues.

Adjustable Flex – The boot's flex is rated on a simple scale of 1-10 (10 = stiffest). Change a boot's flex by simply switching the tongue (additional tongues sold separately).

Infinite Pivot – Unlike traditional designs, the rear cuff never bottoms out. It pivots infinitely forward with your calf for less shell distortion, no shin pain, and more control.

Ribbed Tongue – 100% ribbed tongue enables smoother, more natural linear flex from your shin to your toe. The tongue bends like a flexible straw, never bottoming out while providing smooth rebound. No more shin bang! Optimized for FT's new 45 degree cable positioning for the smoothest flex possible.


Pro Liner – 4 mm Open Cell Foam / 2 mm Intuition® RD Foam / 7 mm Intuition® HD Foam. Specifically engineered to provide the most energy transfer to shell while maintaining warmth in a light weight and custom moldable fit.

100% Heat Moldable Intuition® – All adult Full Tilt boots use authentic Intuition® closed cell foam that is body heat activated to mold 100% to your feet and shell during use, or can be heat molded by a shop in minutes.

J Bars – An additional J-shaped piece of foam is inserted internally on both sides of the ankle area to dramatically increase ankle hold, to keep your feet perfectly in place for precise control.

Powerwrap – An additional layer of ergonomically shaped High Density Intuition® closed cell foam is wrapped around the outside of the upper liner to provide added energy transfer and horsepower to the shell.

Warm – Unlike conventional liners, Full Tilt 100% foam construction is air tight with reduced seams to retain body heat.

Shell Materials & Design

3-Piece Shell Construction – Up to 2 lbs / 900 g lighter than other boots due to its smart and minimalistic 3-Piece design that eliminates the need for thick, heavy overlapping plastic or bolts.


Lateral Adjustment – Easy, precise lateral angle adjustment up to 12 mm.

Forward Lean Adjustment – Tool-less forward angle adjustment of 3 mm or 7.6 mm.


Widetrack Buckles – New adjustment mechanism engineered to increase precision and durability while maintaining on-the-fly single-handed micro adjustment. New durable aluminum lever with a minimalistic lightweight design.

45 Degree Heel Lock – Keep heels where they belong. Placing the middle buckle at an optimal 45 degree angle creates a solid lock for the heel to stay put when pressuring the tips and tails of the skis.

Cables – Cable closure works like a shoe lace to eliminate dead spots for a smooth even pressure, flex & fit.


Rubber Soles – Natural rubber soles on the toe & heel for non-slip walking & hiking that can even be replaced if they wear out.

Shock Absorber Boot Board – Soft rubber layer in the sole of the shell absorbs vibrations, impact, and shock for a smooth ride.

Additional Features

Customizable – Full Tilt boots are customizable - all parts are sold separately for unlimited personalization and repair using a standard Philips head screwdriver.
