These are high quality running shoes with minor imperfections that have been certified by experts. They will come in new, reduced-waste packaging and the condition of the item will be near excellent, with 99%+ of life remaining. There may be minor signs of wear. This pillar of consistency makes some subtle, yet significant updates in its quest to be the best. A redesigned mesh upper adds breathability without compromising support or lockdown and a more flexible outsole makes for a more natural roll heel to toe. A combination of FlyteFoam and FlyteFoam sits in between and couples with the ever important Dynamic Duomax and Space Trusstic system help support and add stability through overpronation. Still one of the best shoes out there, the Kayano 27 shines brightly among the competition.
