This is a brand new, unused pair of Under Armour spikes that are no longer in production. The right shoe has had toe reinforcement applied. They are lightweight and have a thick sole, making them a new, unused item. I purchased these and kept them as a spare, but I never had the opportunity to use them, so I'm putting them up for sale. My impression after trying them on is that they are 28.0cm, but I feel they are the best pair for people with high insteps who usually wear 26-27cm shoes, as they can be worn without fatigue. These are rare items that are not available on the market, so please purchase them if you are interested. (First come, first served)
