The Air Max Invigor series comes in a variety of colorways, including options like Grey/Pink, White/Silver, and Black/Silver, among others, depending on availability.

Ensure you have the correct size. Wear with thin socks initially to allow for a slight stretch. Laces can be adjusted for a more personalized fit.

This can sometimes occur due to friction between parts of the shoe. Try walking on different surfaces to see if it persists. Ensure the insoles are properly seated.

Gently clean with a soft brush and a mild soap and water solution. Blot with a clean, damp cloth and allow to air dry.
