2 reasons not to buy

  • The fit and the sizing of the shoe did not follow the brand’s standard measurements; it was too narrow for a few wearers while the length was longer compared to other models of the same size.
  • Some users complained that the Adidas Crazy Power RK was not meant to be used for dynamic workouts because the sole unit was too stiff.

Bottom line

In general, gym-goers were quite pleased with how stable the Adidas Crazy Power RK was for weight training. Shoppers found it to be useful for other types of workouts, not just for squatting or lifting weights. On the downside, there were some who thought that the platform was too rigid to be used for other forms of exercises. Another issue that purchasers had with the footgear was the inconsistent sizing and fit. But in the end, it came highly recommended by strength training aficionados.

Updates to Adidas Crazy Power RK

  • The Adidas Crazy Power RK is the updated version of the discontinued Adidas CrazyPower Weightlifting Shoes. It retains a similar silhouette as its predecessor, but the material used on the upper has been changed from a smooth fabric to a textured fabric that delivers a close-fitting feel.
  • The TPU (thermoplastic polyurethane) is used in many instances throughout the trainer. It serves as the midsole wedge that lifts the trainer at the heel. The element is also used as a heel counter that keeps the foot steady and as an overlay on the forefoot to protect the toes from abrasion and impact.
  • The bottom of the footwear is lined with a durable, anti-slip rubber. This compound does not get easily worn out and keeps the foot planted to the ground.

Adidas Crazy Power RK size and fit

The Adidas Crazy Power RK only comes in men’s sizes, from US sizes 6 to 15. For the width, it is available in a D - Medium profile. The upper is made to fit like a sock, offering full support that expands when needed. The lacing system and the single wide strap at the top of the midfoot heighten the snugness of the upper.


The outsole of the Adidas Crazy Power RK is made of anti-slip rubber. This compound is hard-wearing and has a tread pattern that enhances the grip of the rubber. It also features flex grooves that allow for more natural movements. The heel flares out to deliver a wider base that steadies the rearfoot.


The Adidas Crazy Power RK uses a TPU wedge at the heel. This element gives the shoe elevation at the heel, angling the foot so that wearers can squat deeper and their feet feel more planted to the ground. The component is firm and does not easily get compressed, keeping the foot steady during certain strength training moves.


The textile upper is designed to be durable and deliver a sock-like fit. It has TPU overlays at the toe box to protect the toes. There’s also a mesh overlay at the forefoot that keeps the foot locked in place and maintains a breathable interior.

The Adidas Crazy Power RK employs a lacing system that allows users to customize the fit. The single hook-and-loop strap at the midfoot is broad enough to encompass much of the instep and keep the foot locked down. It also heightens the lateral support of the upper.
