The Salomon X Ultra Pioneer Aero W is the versatile hiking shoe for women who prioritise breathability and lightweight performance without giving up X-ULTRA family technology: a breathable anti-debris mesh upper, a Mud Contagrip® outsole built for mud and demanding terrain, advancedCHASSIS™ for stability and a SensiFit™ fit that holds the foot precisely in place on every descent. Loaded with technology and versatile enough for both the trail and everyday adventures.
Active breathability for membrane-free adventures
The anti-debris mesh upper ensures continuous foot ventilation, drawing away heat and moisture during activity to maintain comfort on long routes and in warmer conditions. The tight-weave fabric prevents dust and fine particles from working their way between the foot and the footbed, while the soft textile interior lining adds durability and comfort. The ideal choice when waterproofing is not required and keeping the foot cool and fresh is the priority.
X-ULTRA stability and cushioning
The advancedCHASSIS™, a moulded insert embedded in the outsole, connects directly to the base of the shoe to stabilise the heel and provide powerful lateral support without restricting the natural movement of the foot. Surrounded by EnergyCell™ foam cushioning, the system absorbs impact with every stride and delivers good energy return, making this shoe a reliable companion on both technical climbs and the most demanding descents.
Mud Contagrip® outsole and precise SensiFit™ hold
The Mud Contagrip® outsole combines two rubber compounds and a chevron lug pattern specifically engineered to penetrate and shed mud, delivering traction and control in wet and loose terrain. The patterned heel adds extra grip for safe braking on descents. The SensiFit™ system wraps the foot from the midsole to the conventional lacing system for a secure and customisable fit, while the protective rubber toe cap reinforces the highest-wear zones.

TECHNICAL INFORMATION
- Anti-debris mesh: High-density tight-weave mesh that prevents dust, sand and fine particles from working between the foot and the footbed during movement. Simultaneously allows active foot ventilation — a key feature in this membrane-free design.
- advancedCHASSIS™: Moulded insert embedded between the outsole and midsole, connecting directly to the base of the shoe to stabilise the heel and provide powerful lateral support without compromising the natural mobility or flexibility of the foot.
- EnergyCell™: High-performance EVA foam in the midsole that surrounds the chassis and absorbs repeated impacts with every stride, delivering cushioning and good energy return to reduce fatigue on long routes.
- Mud Contagrip®: Rubber outsole specifically designed for mud and wet terrain. Combines two rubber compounds and a chevron lug pattern that penetrates and ejects mud effectively, delivering traction and control even in the slipperiest conditions. The patterned heel reinforces braking performance on descents.
- SensiFit™: Upper construction system that wraps the foot from the midsole to the lacing system, providing a secure, comfortable and virtually customised fit all around the foot structure — particularly effective on technical descents.
- Molded OrthoLite®: Interior footbed moulded to match the contours of the foot, providing superior cushioning, breathability and durability over standard textile insoles.
