Summary
A freetouring model that fully embodies modern trends in ski mountaineering: enjoying the descent without too much of a struggle on the ascent. It is precisely its position in this middle ground between touring and freeride that makes it a boot for advanced skiers, offering versatility thanks to its ability to adapt to different bindings: pin, freeride, and alpine.
Pros
- Precision on descents
- Good mobility
- Comfortable fit
- Sustainable materials
- Compatible with piste bindings
Cons
- Limited roll when walking
The Sender is La Sportiva’s freetouring model designed for those seeking a good balance between uphill efficiency and downhill performance. Its weight places it in the advanced touring category, but its four-buckle construction and shell stiffness bring it closer to a freeride boot.
Precision is ensured by the four-buckle adjustment and the power strap on the shin, while the tongue design promotes direct power transfer even on wide skis. Bio-based materials help keep the weight down while offering good thermal protection.

Test mode
I used the Sender skis between February and March in the Alps, for ski touring, freeriding, and on-piste skiing. Conditions were mostly soft snow, sometimes deep, with ungroomed sections typical of some French resorts.
The test was conducted using Black Diamond Helio Carbon 95 mm skis with ATK Raider 13 bindings and Faction Agent 2 (96 mm) skis with Plum bindings.

Construction
The Sender features a sturdy construction, clearly inspired by the world of freeriding. Four-buckle configuration immediately conveys precision and support, setting it apart from touring boots that prioritize lightness.
The weight, around 1530 g, remains reasonable for the category. Shell combines Pebax® and Grilamid reinforced with bio-based carbon, offering a good balance between stiffness and weight.
The fit is quite roomy, facilitated by the front opening of the tongue, and prioritizes comfort without compromising control. The Force Wrap™ system improves shin wrap and power transmission, a key element for skiing.
Liner
The inner liner uses dual-density Ultralon® foam, ensuring comfort and excellent thermal properties. The fit is snug but not too tight, designed for extended use.
It is thermoformable, allowing you to further customize the fit to the shape of your foot.
Sole
The GripWalk® sole reinforces the boot’s hybrid nature. Compound offers good grip on snow, ice, and rock, while the tread is durable and deeply grooved.
The geometry remains fairly flat with minimal rocker: it prioritizes stability and power transfer on skis, but slightly compromises roll-off when walking.
Compatible with pin, freeride, and new-generation alpine bindings (Multi Norm / GripWalk), ensuring versatile use.
GripWalk vs. ski mountaineering sole
The GripWalk® sole differs from a classic ski mountaineering sole due to its flatter and stiffer geometry, designed to improve power transfer and ensure compatibility with alpine and freeride bindings.
Ski mountaineering soles with Vibram inserts, on the other hand, prioritize grip and rolling motion while walking, making them more effective on mixed terrain and during approaches, but less responsive when skiing.
The choice of the GripWalk sole for this model contributes to the hybrid nature of the product, making it a truly multi-purpose boot suitable for various terrains and setups.
Uphill performance
In walk mode, the Sender impresses with its efficiency. The 64° knee articulation allows for a wide, fluid stride even on long climbs.
Its light weight for its class and good mobility make it well-suited for significant elevation gains, though it is geared more toward downhill riding than fast climbing.
Downhill performance
It is on the downhill run that the Sender truly comes into its own. The four-buckle closure system, combined with the Force Wrap tongue designed to securely wrap around the foot, ensures direct and effective power transfer.
The high flex delivers a precise, stable, and responsive boot capable of handling wide skis and high speeds. Even in variable snow conditions, support remains consistent.
The adjustable angle (12° / 14°) allows you to tailor the fit to your skiing style. The overall feel is closer to an alpine boot than a classic touring boot.
Walk
When walking, the limitations of a freeride-oriented boot become apparent. The grip is good, but the roll feels less natural due to the sole’s lack of rocker.
Closure
The closure system features four micrometric buckles and an upper strap, allowing for precise adjustment along the foot and shin.
Buckles can be kept in an open but secure position during the ascent, while the strap provides enhanced support at the top. The system remains easy to use even when wearing gloves.
Sustainability
The use of bio-based materials such as Pebax® Rnew and Grilamid reduces environmental impact without compromising performance and durability.

Fit
The fit is snug and stable, with good support across the entire shin and effective foot lockdown. For wide feet, heat molding may be helpful.
Despite the rigid construction, the boot is easy to put on thanks to the wide front opening and soft tongue.
Recommended for
Ideal for advanced skiers looking for a freetouring boot geared toward downhill skiing, capable of combining good efficiency on the ascent with high precision on the slopes.
It can be a true multi-purpose boot, for those who push hard on the descent and want to move around—thanks to the GripWalk sole—even on the groomed slopes without having to change their entire setup.
It remains, however, a true ski touring model, obviously designed for structured skis and for skiers who prioritize the enjoyment of skiing over the stopwatch on the ascent.
