Japanese Zen Gardens Inspire The Nike ISPA Sense Flyknit 。The ISPA Sense is your ticket to tranquillity. Mixing sustainable materials (it\'s made from at least 20% recycled content by weight) with meditative comfort, the design pulls inspiration from Zen gardens. The plush midsole delivers extra calm with its sand-rake pattern. The bootie-like upper personalises the comfort. The airy Flyknit design integrates zonal venting and padding for extra on-foot bliss. Tie it all together with the sleek lacing system and then stay upright with added traction on the outsole. Do good, look good and overcome the urban environment\'s most challenging obstacles with this fresh design that gives new meaning to rest and relaxation.
