Nike Air Zoom Vomero 5 - Grey - UK 5.5

TecTuff technology is a durable coating applied to materials, often in footwear, to enhance resistance to abrasion and scuffing, thereby extending the shoe's lifespan.

Zoom Air is Nike's proprietary cushioning technology that uses pressurized air pockets within a durable membrane in the midsole. It provides responsive cushioning and a springy feel with each step.

The Zoom Air cushioning in this model offers responsiveness but is considered subtle. For marathon running, which requires maximum cushioning and impact protection, you might consider models specifically designed for long-distance endurance.

Ensure there is about a thumb's width of space between your longest toe and the end of the shoe when standing. The shoe should feel snug but not constricting, with no heel slippage.

No, machine washing is not recommended as it can damage the materials, construction, and cushioning of the shoe. Hand clean them following the care instructions.

This refers to the colorway. 'White' is the primary color, and 'Vast Grey' is a secondary shade used for accents and details on the shoe.

You can check the Nike website or authorized retailers for other available sizes and colorways of the Air Zoom Vomero 5 series.

Ensure laces are loosened before putting on. If still tight, consider if this is the correct size or if the shoe requires a break-in period.

Verify you are wearing appropriate socks. If discomfort persists, the shoe may not be the best fit for your foot type or intended activity. Allow a brief break-in period.

Gently wipe the affected area with a damp cloth. For tougher marks on TecTuff areas, a specialized sneaker cleaner might be used carefully.

Check the outsole for embedded debris and clean it. Ensure the surfaces you are walking on are not excessively slick. The outsole wear is normal with prolonged use.
