About this product
Foam is what the upper is made from on Nike's Ja 4 Halloween, and foam is generally light, a little yielding under the hand, with a moulded surface that can look smooth or faintly textured. Made for men, the 2026 pair closes with laces and has a rubber sole. Rubber is denser than foam and firm to the touch, and it can scuff or take marks with use. Cushlon 3.0 foam and a Sprpwr insole are part of the shoe as well. Halloween is the colourway, a title rather than a written set of shades, so the pair is known by that name, the foam upper, the laces and the rubber sole. The Halloween name stands in for any further hue detail.
