BEST FOR: Big feet, mellow trails, midfoot strikers.
THE TEST: We’ve found previous Ecco trail runners to be a bit clunky, but several testers raved about the fit of the new Krypton—a firm, low, natural-feeling shoe that remains stoutly protective on rocky trails, thanks to a thick, stiff rubber outsole. The Krypton has a noticeably roomy last—wide at both forefoot and heel—which means that this shoe will feel most secure on high-volume feet. The downside? All that extra room made the shoe a little sloshy on off-camber terrain, and the stubbornly hard-to-adjust laces didn’t help.
THE VERDICT: The roomiest shoe here. It felt best on flat trails, but some testers found it too stiff. 11.2 oz; 8 mm drop
