Product Info

The all new K2 Recon 140 BOA Ski Boots represent the pinnacle of K2's approach to fit and performance. They're the stiffest boots K2 has ever produced, and the 140 flex should leave no skier wanting for more when things get rowdy. That burly flex is complemented by a plethora of cutting edge technology, including BOA closure on the lower shell and Intuition PowerFit Wrap BOA liners which cinch down to keep your heel locked in place. For demanding freeriders seeking the best of the best, nothing else compares.

Product Details


MultiFIT Last: 97 - 100mmThe MultiFit Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes ranging from 97mm to 100mm eliminating the need for multiple last option (LV, MV).

FastFIT InstepSofter TPU material is used in the instep area of select models' shells for quick and easy entry and exit.

Fully Heat Moldable


Flex: 140A very stiff flex for the most aggressive skiers.


Intuition PowerFit Wrap BOA®BOA liner increases adjustability and hold across the entire foot. Features stiffer foam with a full wrap design for added power and energy transmission. Completely heat moldable with pre-molded ankle pocket.

Shell Materials & Design

ShellTPU (Thermoplastic Urethane)


PowerLite ShellThe shell is purpose-built to result in the best skiing, lightest weight boots ever produced. Made with four different stiffnesses of TPU and optimized wall thickness profiling, the Powerlite Shell achieves a paradoxical balance of lightweight agility and power. The resulting boots weigh in as some of the lightest alpine and freeride on the market, yet they ski with all the power and drive of heavier boots.

PowerFuse SpYneA rear co-injected “Y” shaped design that adds strength and power to the Energy Interlock, the PowerFuse SpYne maximizes fore/aft flex efficiency and lateral stiffness for sustained performance and responsiveness in all terrain. Because of the SpYne, K2 is able to optimize materials in the cuff and shell, eliminating excessive vibrations in rough terrain.

Power Plate


2 Light Alloy Upper Buckles

BOA® Fit SystemThe BOA® Fit System provides a performance fit engineered to enhance feel and responsiveness while reducing pressure points by incrementally modulating the Alpine boot closure with precise micro-adjustments.

H+i1 DIALProvides micro-adjustable, precision fit and quick release, with quality and durability guaranteed. The BOA dial platform features a breakaway design engineered to eject the dial cartridge upon severe impact without damaging the system, allowing skiers to pop the dial back into the bayonet midmountain. In the unlikely event that the system is broken, it can be easily repaired and replaced.

Power Strap

Cam Booster Powerstrap

Bootboard & Footbed

Modular Honeycomb BootboardThe honeycomb boot board includes two modular heel inserts. A soft Harsh Mellow insert for a high level of damping or a more rigid insert for improved power transfer.


GripWalk ISO 23223 OutsolesRemovable and interchangeable rockered soles designed to work with GripWalk binding systems for better grip and comfort while walking, standing, and hiking.
