Comfortably efficient.

When looking for mountain biking shoes, comfort and efficiency are the two most important criteria to consider. With their solid uppers, fiberglass-reinforced soles, and inimitable Dynalast design, the Shimano SH-XC31 Mountain Bike Shoes meet them both. The XC31s' knack for smoothing the trail is appreciated, but the shoes' real star is their inclusion of Shimano's Dynalast technology at such a forgiving price point.

Dynalast increases your pedal efficiency by a claimed .56%. While that doesn't seem like much at first blush, any cyclist who's ridden for longer than two hours understands the importance of marginal gains like this. They can be the difference between finishing a group ride or race at the front or struggling to hang on. Dynalast involves lowering the toe-spring and heel section of the last while keeping the arch and metatarsal areas at the same height. This creates an optimal pedaling angle for leading into and exiting the up-swing of your pedal stroke, so the dead spot is shortened and your efficiency is increased with each turn of the crank.

The polyamide outsole is reinforced with fiberglass threads to strike a balance between stiffness and the amount of vibration that it transfers to your feet. After all, energy transference is a two-way street, so while the XC31s aren't ideal for a one-hour hammerfest race, they will keep you comfortable in the saddle for half-day adventures. It's mated to a synthetic leather upper that beats its natural counterpart in every aspect where it counts. The synthetic is less-stretchy, more durable, and lighter, so the XC31s' ability to resist deformation and shrug off grasping twigs and the occasional chance encounter with a rock or trunk doesn't come at the expense of weight.

Good shoes, Great service

  • Familiarity: I've used it once or twice and have initial impressions

I've only used shoes once but they seem to be what I was needing and fits well. This is more for competitive cyclist than the shoe. Great service - they called soon after purchase to make sure all was well and then upgraded my shipping to 2 day and waived the shipping cost. Didn't get much of a chance to say thanks when they called - was in middle of something. It was much appreciated.


  • Familiarity: I've used it several times

Entreno todas las semanas y hago viajes de media y larga distancia. La verdad que tanto en el día a día como en largas jornadas se sienten muy cómodas. Recomendables.
