GAMMA GTX

Price: $225

A women’s specific waterproof, lightweight lithe hiking boot for unencumbered freedom on the trail

An Italian made backpacking boot that is supportive for big loads yet light and flexible

A Gore-Tex® boot that is super flexible and extremely comfortable for day hikes, backpacking or trekking in the high mountains or where there are no mountains. 

The Gamma has a women’s specific last that works beautifully with the ergonomically sculpted PU/EVA midsole that has soft EVA inserts in the heel strike and forefoot areas. 

This shoe more closely mimics a running shoe then it does a hiking boot in feel but the protection is ideal for the trails. 

3D Flex™ uppers let you maneuver on off camber terrain with excellent articulation and the Vibram® Sasslong outsole provides grippy traction on uneven terrain.

Symbios Technology

 The ideal footwear for the mountains weighs the fine balance between protection, comfort, flexibility and technical proficiency.  To design the perfect symbiotic relationship between materials and design that allows the foot to move freely while still providing support and protection is the ultimate goal in footwear design.  The new Symbios technology was conceived to create a better fitting product by improving the fit of the upper on the foot. We started with a new co-molded PU and EVA ergonomically shaped midsole which provides a lightweight form-fitting platform.   Supportive in the appropriate places and soft and flexible where it counts, this midsole provides lightweight stability required for high end backpacking and trekking.  The ergonomic construction process extends to the upper with a new 3D ergonomic form fitting last, which hugs the foot and provides the best-fit possible.   The upper is designed with a 3D Flex ankle to provide optimal articulation for technical terrain and a stretch Cordura® fabric to enhance breathability while maintaining a stable platform for heavy loads.  The tongue construction has been engineered to reduce bulky fabric overlays in the gusset by using stretch materials to create a smoother, more uniform fit.  The end result is a better fitting product that offers more support and structure without using motion encumbering heavy materials as stiffeners in the midsole and upper. This creates a product that is perfect for day hikes or multi-day outings with a heavy backpack.  All of these elements work in a symbiotic relationship to create the SYMBIOS SYSTEM that is a new cross over philosophy of making boots for mountain activities.

I really love this boot in the sense that it's super light and very rugged. It is extremely hard to break in though. I have had a variety of different hiking boots in the past, and have never had a more difficult time breaking them in. I wore them on a backpacking trip to Isle Royale National Park and made it 7 miles in them before they wore holes in the back of my heels, so bad that I had to hike the rest of the island in my sandals. Now that they are more broken in, I love them more and more. I am all about light and fast, and they are perfect for that. Just make sure you take more than enough time to break them in before a trip.
