Size and fit

The Reebok 3D OP.Fractional is available in men’s sizes. Women who are planning on grabbing a pair should go down one and a half sizes from men's. The sneaker’s low-cut design gives the ankles a freer range of motion while its knitted collar embraces the foot with a snug, sock-like fit.

Reebok 3D Op.Fractional Style

Dive into the 1990s Reebok classics, and see how people styled the original Opus model in that decade. Considering its heritage, the Reebok 3D OP.Fractional easily blends in with the 1990s baggy fashion—namely, a loose-fit pair of jeans, hanging trousers, or any free-flowing shorts or pants.

However, since the sneaker is also as modern as it is a classic, one could flaunt these eye-catching Reebok sneakers for that fashionable urban look. Skinny jeans and tapered-down joggers would be good choices.

The Reebok 3D OP.Fractional is available in two colorways: Chalk/Green/Grey and Cool Grey/Chalk/Green.

Notable Features

The Reebok 3D OP.Fractional is a product of extensive design development. As such, the sneaker has a futuristic-looking silhouette. Its upper comprised of woven and twisted Merino wool, with suede and genuine leather precisely layered at the upper’s wear areas. This minimalistic upper sits atop the chunky graphite split-tooled sole, which features contrasting colors at the heel and the forefoot and a 3D Ultralite EVA foams for its midsole.

Reebok 3D Op.Fractional History

During the 1980s and 1990s, leading footwear brands were introducing futuristic-looking designs, some which almost looked too bizarre. It was during this time that Reebok boldly stepped forward and invented the split sole technology. In 1992, Reebok released the Pump Graphite, which first featured this iconic split outsole.

The intriguing split-sole silhouette defied conventions as the middle of the sole is missing. As a result, the Pump Graphite had weighed considerably lighter and had less bulk in it compared with other sneakers. These split sole technology made the sneaker a lot comfortable, stable, and flexible.

Reebok followed up the Split series in 1994 with the release of the Instapump Fury, considered to be the most iconic of the Split series and the progenitor both the famous Pump line and Fury line. Aside from having the famous split sole, the Instapump Fury became also the first shoe to use air rather than shoelaces to lock the foot into the sneaker. With the Pump technology, the Instapump Fury inflates and deflates its chambers to offer the foot a personalized fit.

The Reebok 3D Opus (or OP.) was launched in 1998. It was a split-soled beast of a shoe characterized by a maximalist design with an aggressive line and unexpected paneling. That means to say that the sneaker is chunky as could be, looking like dad sneakers.

Twenty years later, Reebok dug into their archives and revived the Reebok Classic 3D OP., freshly renaming into the 3D OP.98. That same year, the Reebok 3D OP.Lite was released. It was a pretty minimalistic sneaker but which paved the future Opus oeuvre toward being more lightweight.

From the blank canvas of the Reebok 3D OP.Lite came forth the Reebok 3D OP.Fractional, which features a part-knitted, part-leather upper while retaining the Opus-defining graphite split sole tooling.
