Heel Fit System
The Heel Fit System (HFS) consists of anatomically sculpted pieces of foam padding which hold the heel comfortably and securely in place to avoid unwanted movement.

Trekking boots require a snug fit around the heel area to prevent unwanted movement which can lead to excessive friction and blisters. HFS is a system of anatomically shaped high quality foam padding which helps to comfortably hold the heel securely whilst accommodating different heel shapes.


TPNet is an external TPU lattice structure which is injected into the outer fabric. TPNet is used to add support and protection to the upper whilst adding minimal weight and it allows for maximum breathability.

TPNet is a lattice of thermoplastic polyurethane which is injected into the outer fabric.

This TPU lattice creates an exoskeleton like structure which stiffness the fabric. TPNet may be used to provide ample lateral ankle support around the heel area of a lightweight boot with minimal weight. TPNet is very durable also serves to protect the underlying fabric from abrasion. Since TPNet is injected into the fabric rather than glued the bond is permanent and will not delaminate. The large holes in the TPNet lattice allow for much better breathability than traditional non-permeable reinforcement layers.


Our all new improved version of the Hurricane is unlike anything else! Using revolutionary construction techniques and unique materials we have created a boot which takes comfort, breathability and low weight to unprecedented levels. Hurricane offers the same underfoot support as a regular hiking boot, yet incredibly it weighs less than many approach shoes.

  • USAGE: Light weight Trekking, ultra light backpacking, fell walking, 2-3 season use. Travel

  • ​WEIGHT: ​1069 grs./pair (size 7 UK)


  • The upper is made from a unique high-tech three layer laminate material with a Sympatex® waterproof breathable membrane and a hydrophobic mesh lining. An injected TPU lattice provides great support and protection to the upper with minimum weight and an injected rubber toe cap adds useful protection. 

  • The very low number of seams and soft nylon tape lace loops gives Hurricane an outstanding sock like fit, and the breathability of the upper to moisture vapour far exceeds the performance of traditional waterproof designs.
    Hurricane is fully board lasted with a full length midsole, just like our other hiking boots and so offers the same high level of underfoot support on rough ground. The midsole has a soft polyamide monofilament top-layer surface which not only adds extra underfoot cushioning but also improves the transport of moisture away from the underside of the foot. The lightweight Vibram® Borealis sole unit combines superb shock absorption with an aggressive tread pattern for great traction on both hard and soft surfaces and features an integrated injection molded piece in TPU which improves torsional stability.
