i cant tell you what year they came out but there were 4 shoes in that pack: the AP Gel Epirus, the AP Gel Lyte, the AP Gel LD Racer, and the Lyetrac competition spike...i have a Deadstock AP gel lyte with box and brochure but there is no date attached...and i also have two pairs of the AP Gel LD racer, but without boxes (got them for a steal at $5 each at a flea market two years ago, the AP gel lyte, i got off ebay a bunch of years back). all 4 shoes have the same colorway and the brochure says "The asics performance package." the brochure also has some pics of matching athletic gear to the pack (jackets, pants, duffel bag, etc.)...they are all made in korea.
the shoe pictured above is not actually a gel racer but it is the "AP Gel Epirus"...my guess is from the late 80's..they also came with white laces..
i also have two pairs of gel epirus, but not that colorway/pack.
here's a crappy pic of my AP gel lyte...i dont have any pics of my gel racers.
Thanks for shedding some light on these, I love the look of these and now that I know the name of them I can search deeper. Yea they have a "Made in Korea" tag in them, and they are actually wearable. Just wish they came with the box. Thanks again...
