The SLX Zone is a new relative to the wellestablished Harambi. It shares the same upper pattern—though here it’s a new open mesh—and the same midsole: a nice, cushy layer that softens the effects of synthetic tracks.

The outersole shows divergence from its sibling, as the plate provides a weight savings by eliminating much of the thermoplastic and using only three small sharkskin patches that cover about 30% of the outersole. The perimeter of the forefoot features 4 spike wells that encircle a forefoot of polyester-backed TPU embossed with dozens of tiny, plussign– shaped lugs for additional grip. The combination of light weight, cushioning, great flexibility, and effective traction make the SLX Zone a good distance spike choice.
