Nike Air Max 90 Trainers - Brown/Black - Size 11

'Prm' typically stands for 'Premium', indicating that this version of the Air Max 90 uses elevated materials and construction compared to standard models.

The updated construction aims to create a more structured toe area that is less prone to collapsing and forming sharp creases during normal wear, helping the shoe maintain its aesthetic.

While the Air Max 90 has running roots and features Air cushioning, this 'Prm' version with its premium materials and specific design is best suited for lifestyle and casual wear rather than intense athletic training.

Gently wipe the snakeskin areas with a dry or slightly damp, soft cloth. Avoid harsh chemicals or vigorous scrubbing to prevent damage to the texture.

Nike generally offers a limited warranty against manufacturing defects. Specific warranty details can usually be found on the official Nike website or through the retailer where the product was purchased.

While the rubber outsole offers some protection, the textile, suede, and velvet materials are not waterproof. It is advisable to avoid wearing them in heavy rain or wet conditions to protect the materials.

This model features a combination of textile and synthetic uppers, with suede overlays. It notably includes snakeskin textures and velvet accents, along with a rubber outsole and a textile lining.

Loosen the laces and re-tie them, ensuring they are not overly tight. If the issue persists, consider if the size is correct for your foot. Different lacing techniques can also be explored for minor adjustments.

For velvet, use a soft brush to lift debris. For snakeskin, wipe gently with a slightly damp cloth. Avoid abrasive cleaners or excessive scrubbing which can damage the materials.

This can sometimes occur due to moisture between layers or the insole. Ensure the shoes are completely dry. If the squeak persists, try a talcum powder or cornstarch under the insole (if removable) to absorb moisture.

While the reworked toe box minimizes this, excessive flexing can still lead to creases. Try using shoe trees when not in use and consider different lacing methods to reduce pressure on the toe area.
