Clarks Un Rio Zip Sneaker - Blue - 6.5 UK

The Clarks Un Rio Zip Sneaker is primarily engineered for everyday comfort, casual wear, and light walking. While they offer excellent cushioning, they are not designed for high-impact activities such as running, intense gym workouts, or competitive sports.

For general cleaning, gently wipe down the exterior with a soft, slightly damp cloth. For tougher spots, a mild soap solution can be used, but always test it on an inconspicuous area first. Allow them to air dry completely away from direct heat.

The zip closure is designed for convenience, facilitating easy on and off. When properly closed, it should not negatively impact the fit or the shoe's overall support. The internal construction and footbed are primarily responsible for securing your foot.

Clarks generally adheres to standard UK sizing conventions. However, because individual foot shapes can vary, we always recommend consulting the official Clarks sizing guide and trying the shoes on with your preferred socks to ensure the most comfortable and accurate fit.

Contoured Comfort is a Clarks technology that provides targeted support to the natural contours and arch of your foot. Cushion Plus refers to intelligent, dual-density cushioning strategically placed to absorb impact and provide lasting comfort by supporting key pressure points throughout the day.

The Un Rio Zip Sneaker features an integrated 'Cushion Soft' high-rebound foam inlay that is generally not designed to be easily removed. While some users might be able to place thin, custom orthotic insoles on top, it's advisable to consult a podiatrist for personalized recommendations regarding additional support.

Ensure you are wearing socks of an appropriate thickness. If the issue persists, double-check your size against the Clarks sizing guide. Foot swelling can occur throughout the day, so trying them on at different times might also help.

While designed for comfort, individual foot shapes vary. Ensure the zip closure is not creating pressure points. If you require additional arch support, consider using a thin, orthotic insole.

This can sometimes be caused by moisture or a slightly loose insole. Try removing the insole and sprinkling a small amount of baby powder or cornstarch underneath. If the squeak continues, contact customer support.

The lightweight sole is built for cushioning and flexibility in daily wear. Excessive or uneven wear might indicate usage on highly abrasive surfaces or specific gait patterns. Rotating with other footwear can help extend the lifespan of your sneakers.
