Gray spiked shoes, for soccer. - Color: Gray - Sole Type: Spikes Modal Ceeda Neo, 23.5cm Used for about a year, but the studs are more than 70% remaining as they were mainly used on natural and artificial turf. How about using them as a spare pair for rainy days? There is black staining from the rubber chips characteristic of artificial turf. Overall deterioration is minor. Thank you for looking.
