I used modified Elichrom Rotalux 100x100cm, it gave nice rim lighting.
I also used light painting technique: after flash is fired (do not forget to turn of the pilot lamp!) i just painted with pocket flashlight to highlight the details. took a number of shots, exposure was 4-6 seconds.
I used fishing line to position the trainers (most time-consuming part!)
dark blue gradient is added in post.
