adidas Futurecraft 4D - Trainers - Striped - Black - Grey - UK 5.5

The Futurecraft 4D midsole is created using Digital Light Synthesis (DLS) technology, which precisely engineers lattice structures for optimal cushioning, support, and energy return tailored to specific athletic needs.

Yes, the advanced cushioning and supportive fit make them a viable option for marathon runners, though personal preference for cushioning levels may vary.

The trainers should feel snug and secure, with enough room in the toe box for your toes to wiggle slightly. There should be no excessive heel slippage or pressure points.

It is not recommended to machine wash these trainers, as it can damage the materials and the delicate structure of the midsole. Hand washing with mild soap and water is the preferred method.

The 4D midsole is designed for durability. With proper care and regular use for running, it should maintain its cushioning properties for several hundred miles, though this can vary based on individual running style and conditions.

While this guide focuses on the Triple Black variant, other colorways and styles within the Futurecraft 4D line may be available from adidas and select retailers.

Ensure the laces are adjusted correctly for a snug but not overly tight fit. Try wearing them with different types of running socks. If the issue persists, consider if the size is appropriate or if a break-in period is needed.

Clean the outsole thoroughly to remove any accumulated dirt or debris that might be hindering grip. Ensure the rubber is not excessively worn down.

Tighten the laces, paying attention to the eyelets closest to the ankle for a more secure heel lock. Ensure the correct size has been selected, as a loose fit can occur if the shoe is too large.
