Size 10 - Nike Ja 1 Scratch 2.0 for sale online | eBay。The Nike Ja 1 is Ja Morant’s first signature shoe with Nike. The launch of Ja’s first signature coincides with the departure of Kyrie Irving from Nike’s roster of signature athletes but it looks like the Ja Morant signature line will pick up where the Kyrie line left off. The Ja 1 is very reminiscent of several Kyrie models and will seemingly fill the niche of a “well tractioned, reactive guard shoe” for Nike from here on out. The Nike Ja 1 features a solid rubber outsole with a very aggressive, herringbone-adjacent traction pattern. We have seen very similar patterns on the Kyrie Infinity and Kyrie Low 5. In fact, the rubber compound on the Nike Ja 1 is almost identical to what we see on the Kyrie Low 5, so you can expect similar on-court performance. Traction on the Nike Ja 1 promised to be excellent indoors and outdoors, although the outsole is not built with the most durable rubber we’ve ever seen. But, for however long the pattern will last, you will get great grip out of the Nike Ja 1. Another thing to look out for is dust build-up while playing indoors. The Nike Ja 1 feels like it will be a solid on-court performance basketball shoe. You really can’t go wrong with great traction, solid cushioning, and good materials. It definitely isn’t a shoe that is built for every type of basketball player and will be better suited for smaller shifter players that will get the most out of that traction, reactive cushioning setup, and court feel.
