FAQs

Are these shoes machine washable?

It is recommended to clean these trainers by hand using a damp cloth and mild detergent to preserve the structure of the EVA sole.

Does the shoe run true to size?

The Tensaur Run 4.0 features a wide fit design, which generally runs true to UK sizing standards for infants.

Can these be used for running sports?

While inspired by running DNA, these shoes are best suited for everyday play, walking, and casual movement rather than competitive sports.

What material is the upper made of?

The upper is constructed from breathable mesh and synthetic materials for durability and comfort.

Are the laces functional?

The laces are elastic and do not require tying, working in tandem with the hook-and-loop top strap for a secure fit.

Troubleshooting

Hook-and-loop strap not sticking

Check the Velcro surface for lint or debris; use tweezers or a stiff brush to clear the hooks.

Foot slipping inside the shoe

Ensure the top strap is pulled securely and fastened tight enough to create a snug fit across the bridge of the foot.

Surface scuffing on the EVA sole

Small scuffs are normal for EVA foam; use a damp magic eraser or mild soapy water to gently buff out marks.

Setup, Compatibility & Care

These trainers require no formal setup and are ready to wear out of the box. To ensure the longest lifespan for the product, follow these care instructions: clean the mesh upper regularly with a soft brush to remove dirt and debris. If the trainers become heavily soiled, wipe them down with a damp cloth and mild soap; avoid fully submerging them in a washing machine, as this can degrade the synthetic materials and the bonding of the sole. Ensure the hook-and-loop straps are kept free of lint and debris to maintain their fastening strength over time.
