Boreal Nelion mountaineering boots

Nelion is a traditional mountain boot reinvented for the 21st century to take advantage of the latest advances in advanced modern synthetic materials. The result is an alpine mountaineering boot which has a winning combination of extremely low weight, high comfort and superb durability.


Features:

- Nelion is ideally suited to summer alpine or lower altitude winter mountaineering in less severe temperatures. The upper is made from synthetic microfiber with an injected PVC overlay for extra lateral support and protection, and features our unique Dry-Line® lining which is fully waterproof and has an unrivalled ability to transport moisture vapour away from the foot. Nelion is slightly more flexible than B3 category boots, making it more comfortable for walking and trekking over extended distances.
- The underfoot comfort of the Nelion is further enhanced by a midsole with a soft cushioned EVA top surface for improved underfoot cushioning and thermal insulation.
- The high quality sole unit platform features a Vibram® New Mulaz rubber outsole with extra cushioning under the heel area and built-in system for improved torsional control.
- Nelion is compatible with semi-automatic crampons and is suitable for less technical winter climbing and glacial travel as well as being great for scrambling, mountain walking and general summer alpinism

Technology:

Bi-Flex:
- Bi-Flex is a system developed by Boreal to improve the forward and lateral flexibility of mountain boots around the ankle area. Bi-Flex greatly enhances both the walking comfort and freedom of movement when climbing.
- Mountain boots with uppers made from stiff materials can restrict the natural articulation of the ankle joint causing discomfort when walking and restricting the freedom of movement when climbing.
- Bi-Flex eliminates this problem by carefully positioning panels of soft pliable materials in specific areas of the upper. These soft compressible panels act like hinges to allow the natural articulation of the ankle in both the lateral and fore/aft directions. Hard incompressible components such as lace eyelets are either made from soft textile materials instead or repositioned so as to not cause pressure points or impede articulation. Bi-Flex greatly enhancing the ergonomics and comfort of high ankle mountain boots.

Dry-Line:
- Dry-Line® is much more than a waterproof membrane, it is a unique lining system developed by Boreal with superior performance and reliability. Dry-Line® is exclusive to Boreal.
- Dry-Line® is much more than a waterproof membrane, it is a unique lining system developed by Boreal with superior performance and reliability. Dry-Line® is exclusive to Boreal.
- Dry-Line® combines the waterproof laminate Sympatex 337 professional (a Sympatex® membrane with breathable micro-fibre lining) and a leather or synthetic outer layer. Between the membrane and lining is an air space created by a monofilament pile layer. Moisture vapor inside the boot enters this air space and is ‘pumped’ out of the boot during normal walking action. This vertical chimney like movement of water vapor is a key part of what makes Dry-Line® superior to other membrane systems.

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.
