New Balance gray insoles, made of synthetic fiber for a comfortable fit. I am selling these because I purchased other insoles and will not be using these. They were in a 25.5 cm shoe purchased at ABC Mart in July. I only wore them for a few minutes to try them on. Since these are used items, please refrain from purchasing if you are sensitive to such things. - Brand: New Balance - Model: Insoles - Color: Gray - Material: Synthetic fiber Thank you for looking.
