Setup, Compatibility & Care
To ensure the longevity of your Ultra 4DFWD trainers, avoid exposing them to extreme heat or abrasive debris that could become lodged in the 4D lattice structure. Compatibility-wise, these shoes fit standard adult UK sizing; however, since the PRIMEKNIT upper is form-fitting, ensure you select the size that accommodates your specific foot width. Cleaning should be done by hand using a damp cloth and mild soap. Avoid machine washing or tumble drying, as high temperatures can compromise the integrity of the 4D printing process and the adhesive bonding of the materials.
