Nike Shox Z Calistra Trainers - Beige - Size UK 5.5

The Nike Shox Z Calistra is designed for everyday comfort and light training. For marathon running, specialized performance running shoes would offer more appropriate support and cushioning.

Refer to Nike's official sizing chart and measure your foot length. These trainers are designed for a standard fit, but personal preference for snugness may vary.

No, machine washing is not recommended as it can damage the Shox cushioning system and synthetic materials. Hand-wash gently as per the care instructions.

Shox technology uses hollow columns in the midsole to absorb impact and provide a responsive, spring-like sensation with each step, enhancing comfort and energy return.

Color perception can vary slightly based on screen settings and lighting. The beige is designed to be a subtle, minimalist shade.

The upper is primarily constructed from lightweight synthetic material for breathability and a secure fit.

Wear with thin socks initially and allow the synthetic upper to conform to your foot over time. If still uncomfortable, consider trying a half-size larger.

This can occasionally happen with new Shox systems. Try walking on different surfaces to see if it subsides. If persistent, check for any trapped debris in the sole.

Use a soft brush or a damp cloth to gently clean the Shox columns after each wear. For stubborn dirt, use a mild soap solution and rinse with a clean damp cloth.
