Unisex GS:BLK Running Shoes

When the trail gets nasty, the Speedland GS:BLK Trail Shoe gets to work. Speedland's blacked-out take on its proven GS platform swaps out the standard lugs for a more aggressive 6.5mm Michelin outsole, giving serious traction on mud, snow, and loose technical terrain where most trail shoes start to struggle.

Everything else that makes the GS platform great carries over in full. The dual-dial BOA Fit System lets you micro-adjust on the fly, so locking down for a technical descent or easing off on a flat stretch takes less than a second. Underfoot, the responsive Pebax drop-in midsole molds to your foot over time and delivers a cushioned, energetic ride that holds up mile after mile. Runners who want extra protection and propulsion can drop in an optional Carbitex GearFlex carbon plate, sold separately.

The breathable spacer mesh upper keeps feet cool and comfortable on long efforts, reinforced with high-tenacity fibers in all the right places for durability on demanding terrain. The rockered platform promotes a smooth, efficient stride, and the protective toe bumper adds confidence when rocks and roots are part of the equation.

For runners who spend their time on soft, technical trails and need a shoe that can handle the worst conditions the trail throws out, the GS:BLK is ready to get dirty.
