Nike Cortez - Blue - UK 3.5

While the original Nike Cortez was designed as a running shoe, this lifestyle version is best suited for casual wear and everyday comfort. For dedicated athletic running, consider Nike's specialized running shoe lines.

Refer to the size chart provided by the retailer. These trainers are listed with UK adult sizing. It's recommended to try them on if possible, or measure your foot and compare to the sizing guide.

The upper is constructed from a combination of leather and fabric, with redesigned materials to help prevent deformation.

Use a soft, damp cloth with a mild soap solution. Avoid abrasive cleaners. For stubborn marks, a specialized shoe cleaner may be effective, but test on an inconspicuous area first.

The foam midsole with its iconic wedge insert provides cushioning and general comfort. For users requiring significant arch support, consider adding aftermarket insoles.

While the leather and fabric offer some protection, these trainers are not waterproof. It's advisable to avoid wearing them in heavy rain or wet conditions to protect the materials.

The 'wedge insert' refers to a design element within the foam midsole, characteristic of the Cortez, which provides cushioning and a distinct look.

Ensure laces are loosened before putting on. Wear with thin socks initially. If still tight after a few wears, consider trying a half-size up or seeking professional shoe stretching services.

This can occur due to oxidation over time. Gentle cleaning with a mild soap and water solution or a specialized shoe cleaner may help. Avoid prolonged exposure to direct sunlight.

Squeaking can sometimes come from the insole rubbing against the midsole. Try lightly dusting the insole with talcum powder or cornstarch. Ensure insoles are properly seated.

Wipe gently with a slightly damp cloth. For stubborn marks, use a cleaner specifically designed for leather. Condition the leather afterwards to restore moisture.
