The Nike ISPA Flow 2020 ‘Desert Sand’ utilizes a unique pull-string lacing system to secure the sock-like woven textile upper, featuring embroidered designs and breathable mesh paneling in coppery and rusty hues. Discreet branding hits include ISPA lettering (short for ‘Improvise. Scavenge. Protect. Adapt.’) on the webbing pull tab atop the tongue, along with a black Nike Swoosh on the molded semi-translucent TPU heel clip. A textured foam midsole provides lightweight cushioning with each step.
