Mammut CORE
The base for every confident step, Mammut CORE specialized midsole foams deliver unmatched comfort, responsiveness, and performance.
Not all trails – or runners – are the same. That's why Mammut CORE isn't a single foam, but a system: three distinct formulations, each developed to deliver the right balance of cushioning, energy return, and lightweight performance.
Whether you're hiking to a summit or chasing a PB on race day, each foam has been lab and trail-tested to match the demands of the way you move.
