Men's Footwear

Rain or shine. Street to summit.

Like that running buddy who never bails, the Challenger 8 GORE-TEX says yes to the road, yes to the trail—and yes to rain, mud and snow. Redesigned with more foam underfoot, an improved fit and reimagined multi-directional lug orientation, it’s both smooth on the pavement and trustworthy on dirt. And its GORE-TEX Invisible Fit waterproof membrane means it doesn’t balk at puddles, either. Guess you’re out of excuses.

Cushioned, secure and built to last, the OMM Ultra Shoe is designed for long-distance comfort across varied terrain. A more cushioned ride, durable upper and reliable grip combine to keep you moving well, hour after hour.

The OMM Ultra Shoe is built for runners going longer — where sustained comfort, protection and durability become critical.

Designed with increased cushioning compared to the Trail and Fell Shoes, the Ultra sits on a 30mm stack height with an 8mm drop, delivering a more cushioned platform that absorbs repeated impact and supports efficient forward movement over time. The lightweight EVA midsole is tuned to balance softness with energy return, helping reduce fatigue across extended efforts.

The upper is engineered specifically for long-distance comfort. A soft yet durable two-layer construction accommodates natural foot movement and swelling, reducing irritation over time while maintaining the resilience needed for repeated use. Combined with the X-Lace system, it provides a secure, even hold across the foot without excessive pressure or restriction.

Underfoot, a Vibram LiteBase outsole with MegaGrip compound and Traction Lugs delivers dependable traction across mixed terrain. The outsole balances grip and durability, ensuring consistent performance across long distances and repeated runs.

This is a shoe designed not just to go far, but to keep performing when it matters most — maintaining comfort, control and reliability deep into long efforts.

The VJ IRock 4 has been upgraded with a soft antislip heel to make sure that the shoe shapes better to the foot and that the foot stays inside of the shoe even during the toughest of performances. The upper’s design has also seen some small tweaks to enhance the fit of the shoe.

The VJ Irock has long been the most aggressive VJ shoe without metal studs for softer conditions. Its specifically designed lug configuration gives optimal grip when it's slippery but still sheds loose debris that could otherwise become attached. VJ’s signature Butyl rubber completes the outsole giving the IRock the world-famous grip it is known for.

The Schoeller®-Keprotec® upper featuring aramid fibres is incredibly durable and protective with the Fitlock system providing added protection and a personalized fit around the foot arch. With its precision fit and amazing grip, the IRock has long been an orienteers’ favourite but has in recent years shown its class in everything from obstacle course races to the most technical of skyraces.

With performance in mind, this shoe is best suited for shorter to middle distances in softer terrain and is in a class of its own from snowy descents to muddy trails.
