Air Jordan Zion 4 PF - White - UK 10

'PF' stands for Performance Fit, indicating that these shoes are designed with specific features optimized for athletic performance, often with a slightly wider fit to accommodate movement.

While the durable construction may handle some outdoor use, they are primarily designed for indoor courts. Outdoor surfaces can cause excessive wear on the outsole and cushioning.

It is recommended to refer to the brand's sizing chart and consider trying them on if possible. For basketball, a snug fit is usually preferred to prevent foot movement inside the shoe.

The lacing closure allows for a highly customizable and secure fit, ensuring your foot is locked down during aggressive cuts, jumps, and changes in direction.

No, washing these shoes in a washing machine is not recommended as it can damage the materials, adhesives, and overall structure of the shoe.

The colorway FD0591-100 is described as 'White Black Bright Crimson'.

Lace the shoes less tightly and wear them for short periods to allow the materials to break in and conform to your foot shape.

Ensure the court surface is clean and dry. Check the outsole for any debris and clean if necessary. The shoe's traction is optimized for clean court conditions.

Replace worn laces with a similar length and thickness from a sporting goods store. Inspect the eyelets for any sharp edges that might be causing damage.

Use a soft brush or an old toothbrush with a small amount of mild soap and water for stubborn marks on the upper. Rinse with a clean damp cloth and air dry.
