This is a new insole for the popular Asics DS Light model, either the training shoes or the spikes. I've been using different insoles and kept this as a spare, but I wore out the main shoes, so I'm selling the insoles only. They are new and unused. I don't have anything to measure the size with, so I'm not sure of the exact size... but based on a measuring tape, I think it's around 22.5cm. Please consider this item, understanding that it has been inspected and stored by a private individual. - Brand: Asics - Color: Black - Size: Approximately 22.5cm Thank you for looking. I have two pairs at home, so I've numbered them.
