Nike Blazer Mid '77 Jumbo - Black Bright Crimson - Trainers

The primary upper material is leather, with suede accents on the toe. The collar features an elastic fabric construction, and the sole is made of rubber.

Use a specialized suede brush or a suede eraser to gently remove dirt and restore the nap. Avoid using water on suede as it can stain or alter the texture.

While the Blazer is a heritage basketball silhouette, the 'Jumbo' version is primarily designed for casual wear. It may not offer the performance support required for intense basketball play compared to modern basketball-specific shoes.

The 'Jumbo' designation typically refers to the exaggerated design elements, such as the oversized Swoosh, and potentially the enhanced comfort features like the elastic collar.

The elastic collar provides a snug, sock-like feel around the ankle, making the shoe easier to slip on and off while ensuring a comfortable and secure fit.

The primary color of the upper is black, with bright crimson used for the exaggerated Swoosh and some accent details. The outsole is predominantly sail-colored with green sawtooth details.

Sizing can vary slightly between individuals. It's generally recommended to consult Nike's official sizing guide and consider reviews that mention fit, especially if you have wider feet, as the sock-like construction can be snug.

Ensure the elastic collar is fully stretched. Gently pull the heel tab while sliding your foot in. If the fit is too snug, consider a half-size up if available.

This can sometimes occur with new leather shoes. Try wearing them for a few days to break them in. If the noise persists, check for any debris trapped in the sole or ensure laces are not tied too tightly.

For minor scuffs, try using a leather conditioner or a specialized leather cleaner. For suede areas, use a suede eraser and brush.

Clean the serrated sawtooth pattern on the rubber sole with a brush and water to remove any dirt or debris that may be impeding traction.
