115-Flex Medium-Volume Crossover Boot
Tecnica Zero G Decoy 115 W GW Alpine Touring Boot
The Tecnica Zero G Decoy 115 W GW Alpine Touring Boot is the crossover boot in the Zero G line, built for skiers who want one boot for resort days on GripWalk bindings and touring days on pin bindings. A polyurethane shell with a polyurethane cuff on a 99 mm last drives a 115 flex, and a robust Power Frame is what lets it hold an edge on a wide ski rather than folding. At 1,510 g per boot in a 24.5 with 65 degrees of cuff rotation and a Vibram GripWalk sole carrying low tech inserts, it walks better than an alpine boot and skis harder than most touring boots.

Why We Like It
- The dual-compatibility sole is the reason to buy it: a Vibram GripWalk sole with low tech inserts runs GripWalk and MNC bindings on alpine skis and pin bindings on a touring setup, from one boot.
- Tecnica gives this shell a more robust Power Frame than the rest of the Zero G line, which is what holds a 115 flex together when you are driving a wide ski.
- Full C.A.S. shell and liner means micro-cell textured surfaces that grind and heat-mold easily, so a 99 mm last can be opened up where a foot needs it rather than being a fixed shape.
- 65 degrees of cuff rotation is a genuine touring range, and the shell alone weighs 1,180 g at 24.5, which tells you how much of the 1,510 g total is liner you can change.
Best Uses
- One-boot setups covering resort and backcountry
- Driving wide skis on firm snow
- Side-country and short tours off lift-served terrain
- Medium-volume feet that want a shell they can modify
Bootfitter's Advice
The Tecnica Zero G Decoy 115 W GW Alpine Touring Boot fits as a medium-volume boot on a 99 mm last, which is narrow enough to hold a foot properly and, because it is full C.A.S., among the easiest shells we work on. The micro-cell textured surfaces grind and punch predictably, so a 99 mm last suits more feet here than the number suggests. Confirm size with a shell fit rather than converting from a street-shoe number.
Plan on molding the liner. The floating tongue construction wraps the instep without the pressure point a fixed tongue creates, and the liner molds quickly and holds its shape. Tecnica does not publish sole lengths for this model, so bring your bindings or your current boot if the setup matters.

Common Questions
Who should buy the Tecnica Zero G Decoy 115 W GW Alpine Touring Boot?
The Tecnica Zero G Decoy 115 W GW Alpine Touring Boot suits skiers with medium-volume feet who want one boot for resort and backcountry. A 115 flex on a 99 mm last with a robust Power Frame drives wide skis on firm snow, and 65 degrees of cuff rotation plus low tech inserts make it genuinely tourable. At 1,510 g per boot in a 24.5 it is a downhill-first crossover rather than a light touring boot.
What bindings work with the Tecnica Zero G Decoy 115 W GW Alpine Touring Boot?
The Tecnica Zero G Decoy 115 W GW Alpine Touring Boot has a glued-on Vibram GripWalk sole certified to ISO 23223 with low tech inserts, so it runs GripWalk bindings, MNC bindings, and pin/tech (low-tech) bindings. It is not compatible with traditional ISO 5355 (Alpine) bindings, and it does not carry an ISO 9523 touring sole, so frame bindings are not an option. That dual GripWalk and pin compatibility is the point of the boot.
Can this boot be used on both alpine and touring skis?
Yes, and that is what it is designed for. Tecnica calls it the most versatile boot in the line because the GripWalk sole works with alpine bindings while the low tech inserts work with pin bindings. One boot, two setups. What it cannot do is a frame binding, which needs an ISO 9523 sole.
What is the range of motion on the Tecnica Zero G Decoy 115 W GW Alpine Touring Boot?
65 degrees, which is a genuine touring figure and more than the Cochise family offers. It is not as free as a dedicated touring boot with a 72 degree range, but for a boot skiing at this flex it is generous.
What foot shape fits the Tecnica Zero G Decoy 115 W GW Alpine Touring Boot?
A medium-volume foot on a 99 mm last. Because the shell and liner are full C.A.S., with micro-cell textured surfaces made for grinding and heat molding, this shell opens up more predictably than most. That means the 99 mm figure suits more feet than it sounds like, but a shell fit is still the way to confirm.
Can the Tecnica Zero G Decoy 115 W GW Alpine Touring Boot be punched and molded?
Yes, and it is one of the better boots we work on. C.A.S. surfaces are designed for grinding and punching, and dual-density materials hold the new shape rather than creeping back. The liner is heat-moldable with a floating tongue that avoids the instep pressure a fixed tongue creates.
What is the sole length of this boot?
If you are matching an existing binding, bring the skis or your current boots and we will measure rather than guess. We will add the chart when Tecnica publishes it.
Our Verdict
The Tecnica Zero G Decoy 115 W GW Alpine Touring Boot is the boot to look at if you have been running two pairs. A Vibram GripWalk sole with low tech inserts covers alpine bindings and pin bindings from one shell, the reinforced Power Frame holds a 115 flex together on wide skis, and 65 degrees of cuff rotation is enough that the skin track is not a punishment. At 1,510 g per boot in a 24.5 it is heavier than a touring boot and it will not take a frame binding, which are the two things to be clear about before buying. For medium-volume feet on a one-boot setup it is a strong answer, and the full C.A.S. shell makes it one of the most adjustable boots in the category.
