Impact Marathon Foundation


When size? created their Alternative Marathon range with adidas Originals, we were blown away to have a shoe created in honour of one of our races. The Guatemala route is brutal and iconic in equal measure - but that is not what makes the race so special. The Impact Runners from across Guatemala, and around the world, are what make this such a unique race day experience. We never set out to make the toughest marathon in the world, though it may actually be that. We set out to create a route that would tell the story of a nation - and, most importantly, empower and uplift communities.

About the shoe

The TRX Runner 'The Volcano' takes you on a trip to Guatemala. Celebrating one of the toughest marathons around, this pair nods to the Guatemala Impact Marathon which sees contestants run through winding farmland and lave-field terrain to reach the lively crater at the summit of country's highly-active Pacaya volcano. The model itself opts for grey and silver shades across its mesh and suede upper, with bright orange highlights on the 3-Stripes. Your feet are kept cushioned by an EVA midsole, and the classic look is rounded off with a studded gum rubber outsole, plus a volcano-inspired print to the footbed.
