Size on the label UK 5,5 (EU 38,5), but I find that Nike trainers size runs  small , so might fit UK 4,5 (EU 37,5).

Silvery grey color with black/ red/ neon orange details.

Slip on model, laces to adjust width.

Slightly used. In very good used condition, with minimum wear. Lightly marked outer soles, one glue mark on the tongue of the right trainer (last photo).
