Run every day on hard, dry and rocky trails in the TRAILFLY, your new go-to shoe for training runs and longer trail races. The TRAILFLY's 4mm rubber studs are perfect for gripping rock and hard-packed, dry ground. These hard-wearing studs have been positioned in such a way to make the shoe faster, by helping you push off at the toe, as well as helping you brake quicker at the heel. The GRAPHENE-GRIP rubber outsole has also been improved from previous models to give better traction in wet conditions. The brand-new anatomical shape of the TRAILFLY hugs the natural contours of your foot, locking in at the heel and widening at the toes for a secure, comfortable feel. Built into that there are two specific fits - Standard and Wide. Go Wide Fit if you have wider feet or like an extra comfortable feel with more wiggle room for toes. It allows for greater comfort when running longer distances, when toes can often swell. The TRAILFLY has a thicker wedge of foam cushioning when compared to its speedier cousin, the TRAILFLY SPEED. This extra cushioning allows you to run further and feel fresher for longer, while also managing to preserve the ground-feel you need when running on technical terrain. A flexible META-SHANK rock plate protects you from painful sharp rocks and tree roots underfoot, allowing you to move confidently over the most challenging of terrains. Ideal for summer and dry weather trail running, the TRAILFLY is a comfortable everyday training shoe that you won't want to take off. Use it for day-to-day running or even for ultramarathons and get a comfortable and protective ride.
