Following the “Red Nebula” from earlier this year, the Reebok DMX Series 3000 returns with a second Brain Child colorway dressed in a blue and yellow gradient over a black midsole.

The colorway traces back to a design pulled from Reebok’s archive in Boston. Brain Child used that reference to bring elements of older DMX trainers onto the current DMX Series 3000, with light blue fading into yellow across the mesh upper. The biggest change from the earlier “Red Nebula” is underfoot, where black replaces the white midsole used on the first pair.

More blue and yellow appears around the tongue and heel, while yellow rope laces run through the upper. Black fills in much of the remaining areas and carries onto the tooling, giving the bright gradient a darker base. The “Blue Nebula” was actually shown earlier in a Brain Child lookbook released around the launch of the first colorway.

The Brain Child x Reebok DMX Series 3000 “Blue Nebula” drops September 25, 2026, at 11 AM ET exclusively through Brain Child. The retail price is $140.
