Share This Page: CJ 81 Trainer Max LAUNCH WEEK 236 lbs. of power can light up fastballs as easily as it pulls in TDs. 4.35 speed could steal bases the same way it streaks past DBs. Calvin Johnson could've brought his elite tools to any field on the planet, but he chose to give everything he had to the gridiron. The CJ 81 Trainer Max launches this Friday at select City Gear stores, and we're beginning to feel the hype. Calvin Johnson's branded training shoe, the CJ 81 Trainer Max (603711-008) has garnered popularity in recent months, but has maintained a limited colorway selection, with only a pair of default colors available so far. This Friday will mark the first new colorway release for the CJ 81 line, with the introduction of the Wolf Grey/White/Orange combo. You can pick this shoe up in select City Gear stores this Friday, August 16, for only $120.
