The UTMB tag suggests these are tough, uncompromising beasts. Tough they may be, but they’re also very soft and cushioned – happy on solid paths, but also ready for off-road action. The FluidFoam technology provides a soft and supple ride, while the grip is perfect for everything from canal paths to dry mountain tracks.
The uppers are suitably abrasion-proof and there’s a slimline, racing-shoe feel to the fit. Given the UTMB approval stamp, the Caldorado III is perfectly happy tackling rocks, roots and uneven ground. Its armoury even includes a rock plate in the forefoot, with an 8mm heel drop.
Road-friendly and capable of tackling the toughest trails.
