There are a number of things enjoying a 20th anniversary this year. Along with Saved by the Bell and the fall of the Berlin wall sits a monumental sneaker development, in the Reebok Pump.

Reebok has just launched a site that’s all about the Pump. They’re also going all out to celebrate the shoe, with a documentary on the Pump by director Colin O’Toole that’s set to release on Nov. 20.

Reebok is giving away 20 pairs of limited edition anniversary editions of the Pump on their Twitter account (@Reebok). Visit their site and follow them on Twitter to stay up to date on the giveaways and their 20th anniversary. And be on the lookout for some fresh collaborations. (Sorry, no hints here, but you can get the latest at here.) And for old time’s sake, enjoy these two old Pump ads from back in the day:

And the specifics from Reebok:

As you probably know, twenty years after the first pair was launched, Reebok is collaborating with 20 of the world’s most iconic sneaker stores to create 20 limited edition versions of The Pump.

The shoes will be available on November 20th. Alongside their limited-edition Pump designs, each retail partner will also offer bring backs of two of the original Pump colorways.
