Nike launched the ISPA capsule in November 2018, a collection that stands for “Improvise. Scavenge. Protect. Adapt.”. The shoes? They’re inspired by and created for the kinds of extreme sports athletes who need their shoes to be as lightweight as possible. The Flow 2020 ISPA trainers are developed based on heat maps of the foot, with an open-weave mesh for breathability, a unique lacing system, and a foam midsole.| Nike woven mid-top trainers100% syntheticLace-up fasteningRound closed toe, contrasting panels, adaptable lace-up design, pull-tab at heelUpper: 100% syntheticLining: 100% syntheticSole: 100% rubber
