Good to know
- The Adidas Crazy Power RK is the updated version of the discontinued Adidas Crazy Power 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 one to deliver a more 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.
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.
