Grey (Speckled heel) Reebok Pump Omni Lite Trainers
Yes, that was a trend at one point. Reebok Pump eliminated the need for the rolled up sock. Originally, Reebok Pump were a basketball shoe. Evidence of this can be seen on the shoes. The actual "Pump" on the earlier pairs was a basketball design. Pairs with that design have been re-released, so if you want a pair with the iconic basketball pump design they are not too hard to find. And some pairs are pretty cheap as well. To name of a few: Reebok OMNI Zone, Omni Lite, Insta Pump Fury, and Solebox Twilight Zone are for sale on eBay and other online outlets.
Reebok Pump Omni-Lite Trainers White / Red
The Pump design is exclusive to Reebok. And I believe that Reebok own the rights to the "Pump" technology built into a trainer so no one else can copy the design. Like Nike Air Huarache, Reebok Pump are another pair of trainers that have gone full circle.
They are very similar to Nike Air Huarache in that respect, very sought after when they first came out, dropped off the radar for a while, and now with most retro vintage trainers making a huge comeback, they are now all the rage again. Reebok are well aware of the demand, hence why there are more new styles and colours out now than ever before.
Reebok Pump Running Dual Trainers
These days the Pump system is not only found on the tongue, but also at the side or, on certain pairs, even at the back heel of the trainer (Emporio Armani xReebok Edition). Basketball Boots and trainer versions of Reebok Pump are available.
If you want a cheap pair of retro Reebok Pump, and you're not bothered about having a pump checkout the pairs of Reebok Reverse Jam, which still have Hexalite technology (Air Cushioning System) incorporated into the soles just like most pairs of Reebok Pump (E.R.S).
