Good to know

The Adidas Crazy BYW is available in men's sizes. This pair has a one-off lacing system with round laces for a snug fit. The knit upper hugs the foot comfortably reinforced with mesh collar, while the ribbed neoprene toe boosts the support.

The flashy mid-top Adidas Crazy BYW features a bold, over-the-top look that once ruled the hardcourt. This fashion-forward footwear delivers a throwback look with futuristic features. The textured upper made of mixed materials delivers an authentic vintage vibe while the robust and wavy 'Boost You Wear' midsole gives that striking 90s athletics element. The unique lacing system reconnects this shoe to its basketball roots.

With this pair's striking silhouette, some wearers opt to style this eye-catching sneaker with simple jeans or joggers and topped with white tees. Others would instead sport this with their activewear for a full athletic guise while staying casually comfortable.

There are just too many noteworthy elements in the Adidas Crazy BYW that make its followers feel crazy about it. This shoe kept connected to its roots by preserving the vintage and futuristic elements.

One would never miss noticing the bulky three pods Boost midsole of the Adidas Crazy BYW. This wavy and daring feature simulates the Feet You Wear (FYW) tech launched in the 90s. Another striking feature is the one-of-a-kind lacing system that is reminiscent of the 90s basketball shoes. And another more notable is the FYW mascot character embossed on the toe sole area.

In 1996, Three Stripes launched the Feet You Wear (FYW) technology in which the shoe acts as the extension of the feet by following the principle of feet's natural movement. This technology was developed by Frampton Ellis, who works outside Adidas and chose to license the FYW for Adidas to use it.

Ellis designed footwear with a wider and lower-to-ground base and curves from outsole to midsole to maximize the stability apt for lateral movements. The FYW features straightforward technology with bold, wavy lines and round shapes.

In 1997, Adidas inked Kobe Bryant and launched his first basketball signature shoe called KB8 using the FYW technology. The brand also used the same tech on multiple sports to highlight its versatility, like the cross and turf training, tennis, and hiking category.

Five years after, the FYW technology developer Ellis and Adidas had licensing issues which caused the FYW line to end. In that short period, the FYW tech ushered the creation of significant models such as Top Ten 2000, KB8, KB8 II, and Key Trainer and now lived in the impressive lineup of retro silhouettes. This tech also paved the way for various brands to develop a minimal approach in emphasizing the natural motion of the foot by providing a barefoot experience to its wearers.

In 2018, Three Stripes launched the Crazy Boost You Wear (BYW) which was inspired by the Feet You Wear tech. The brand kept all the chunky 90s basketball elements to give a vintage vibe and updated with a hefty set of Boost sole.

  • The translucent rubber outsole provides superb traction.
  • The upper is made of ribbed neoprene toe, knit throughout the upper, mesh collar, and hints of suede on the tongue and side overlay.
  • The Adidas Trefoil logo is embroidered on the suede tongue.
