    The MAXx is a well-cushioned, lightweight trail shoe especially designed for longer distances that also works for sprint work. 

    The MAXx has the famous VJ grip with smaller lugs for a smooth ride over all surfaces. The durable upper features a breathable sandwich mesh material designed for durability. The sole has cushioning units in the front and heel for maximum comfort and a full-length rock plate to protect you on tough terrain. 

    Use the MAXx for all surfaces and distances. It is ideal for obstacle course racing, trail and mountain running.

    Totally agree with al the five star ratings. Great for longer distance on the trail.

    Pleasantly surprised

    A nice comfortable shoe out of the box, can accommodate an orthotic, stable and supportive but allows you to feel the ground

    My Go to Trail and OCR shoe!

    Have been running in the MAXx for the last few years now. Have used them from 100 mile trail races to Spartan Stadium races. Love the fit and of course the grip!

    MAXx for OCR

    Had them for 2 weeks and really like them so far. They are as light as racing flats with great support


    love these trail runners. super grippy and solid on rock, mud & pretty decent on snow and ice.
