VFF PRO Overview

The VFF PRO is the preferred boot of Wiley Miller; Professional Skier, DaleBoot Rider & Featured Athlete for Level 1 Productions.  It's designed for skiers who desire a more upright, stiffer boot.  The 10 to 18° flex pattern can be finely tuned to obtain the optimal level for each skier.  The independent flex pattern design allows for progressive forward flexion, while providing an unrivaled lateral stiffness for enhanced power transfer to the edge of a race ski to the widest 'fat boy'.  The overlapping spat system maintains the shell's integrity through all aspects of the turn and the wrap around cuff allows the skier to very easily enter & exit the boot.  All DaleBoot models come standard with the Heat Fit IV liner, in-boot stance balancing in both the frontal (lateral) and sagittal (fore & aft) planes of motion and on-ski cant correction through DaleBoot's replaceable and cantable soles.  DaleBoot utilizes virgin polyether TPU in the construction of all boots, resulting in a very light, but durable shell that maintains modifications for the life of the shell.

The HEAT FIT IV


The Heat Fit IV, designed in conjunction with our partner Intuition Sports, is proprietary to DaleBoot and pre-lasted to the DaleBoot shell during production.  It consists of varying densities of multi-layered Ultralon, cross-linked EVA to produce a fit unlike any other on the market.  Although issued the original patent for foam injected liners back in 1971, DaleBoot left that technology behind as better materials, more suitable to providing higher levels of both comfort and performance were developed and became available on the market.  The Heat Fit IV comes standard with the DaleBoot and is available in three distinct models to best accommodate the widest range of lower leg and foot sizes, dimensions and volumes.  In combination with the exclusive DaleBoot Three Piece Tongue and Instep Closure System, the HFIV provides unparalleled ease of entry, fit, comfort and performance.

The Cuff


63D polyether TPU provides increased stiffness & lateral support over the standard VFF.  The cuff rests at 10°'s, has a maximum forward flex of 18°'s and attaches to the clog at 4 points for optimal alignment with the flex plane of the ankle.  Once ankle biomechanics have been addressed with either the DaleBoot adjustable footbed or by a fully customized footbed, the ankle's flex plane is directly aligned to transfer power to the ski's inside edge.  The alignment of the VFF PRO's flex pattern with the flex plane of the ankle allows the skier to transfer 100% of their power to the proper edge, drastically increasing edge hold, carving ability, and overall performance.

The Clog


Made from 69 durometer virgin polyether TPU, the plastic used in the clog's construction is as stiff as the plastic found in high end, world cup race boots.  The result is a boot that delivers the highest possible levels of frontal plane (lateral) stiffness & stability.  All DaleBoot models are 100% custom made and designed from the skier's foot, outwards to the shell.  Factory-lasted shell mod's, per size, include Length (to +20mm), Width (-4mm to +15mm), & Toe Box height (to +7mm).  The last shape is anotomically correct and can be further customized by a DaleBoot Authorized Fit Center to accommodate all foot forms and shapes.  DaleBoot is the only company using 100% virgin polyether TPU and the result is a very light, but durable shell that maintains all modifications for the life of the shell

The Three Piece Tongue & Instep Closure System

The Three Piece Tongue and Instep Closure System, unique to DaleBoot, eliminates pressure points (or hot spots) along the instep by utilizing varying densities of softer, more compliant polyether TPU on the shin tongue, instep spat and hinge spat.  The progressively softer layers virtually eliminate the possibility of BCS (boot compression syndrome) or nerve impingement, often associated with traditional 4 buckle overlap designs, which causes cold feet, numbness and/or pain.  DaleBoot's Three Piece Tongue and Instep Closure System increases comfort, ease of entry/exit, and eliminates pressure points.

THE CANTABLE & REPLACEABLE SOLE UNITS


DaleBoot's cantable soles provide precise cant correction, neutral balance on the ski and enhanced power transfer to the ski's edge.  Proper cant correction takes into account the physical shape of the leg and the affect it has on weight distribution under foot.  DaleBoot measures the skier's leg shape, to the degree, and cant corrects closest to the snow, by removing the boot's neutral sole units and replacing them with properly canted soles.  The result is a ski that runs flat, allowing the skier to easily engage the ski's edge (in both directions equally) without having to over-angulate their knee, or expose either their MCL or ACL to injury.  After extensive examination and on-ski experimentation, DaleBoot can easily swap out the cant correction for a fill accommodation should the skier's (rigid) skeletal structure refuse to accept a correction.  In addition, DaleBoot's canted soles are also replaceable with extended wear, further extending the life of the boot.

Note: Cant Correction or Fill Accommodation is not to be confused with Cuff Alignment (often erroneously referred to as a "Cuff Cant").  Cuff Alignment is used to match the shape of the boot to the shape of the skier's lower leg (tibial varum or valgum).  It does not offer cant correction, put the skis flat or eliminate over-angulation of the knee throughout turns.  Do not allow a shop technician to "cant correct" you by using a "cuff alignment" mechanism or you could greatly expose your knee to adverse torque and risk injury.

The Adjustable Footbed

As part of the DaleBoot fitting process, the bio-mechanics of the ankle is closely analyzed and measured.  The adjustable footbed, located within the DaleBoot, between the shell and the liner, is then adjusted to account for pronation (eversion of the heel cord), supination (inversion), and/or fore/aft stance balance issues.  These adjustments are absolutely critical to fit, form and performance as they provide optimal stance balancing in both the frontal (side to side) and sagittal (fore/aft) planes.  Neutral balance in the boot allows the muscles to focus on skiing as opposed to maintaining balance, which in turn allows for full power transmission to the ski’s edge.  

In addition, the adjustable insole can also be raised to accommodate slight leg length discrepencies.
