One run shoe (original owner did one run in these and I just tried ‘em on) that I just picked up here on Supwell app. Essentially a brand new Mach 6 and appears quite the shoe - just too tight in toebox for me. $70 or best offer includes shipping to lower 48. A trade will be considered however seeking size 11 only. Road show preferred but open to trail shoe as well. These Mach 6 are mint condition. Real light on foot. A bonifide banger I'd surmise for many a discerning runner. And a Mach version that also appears to be far more durable than prior iterations.
