Thank you for viewing. This is an Under Armour baseball spike. The size is 28.5cm. Although the player is unknown, it is said to have been used by a professional player. - Laser engraving of "3" on the heel - Signs of use I received it as a non-sale item, but I am selling it because the width of the shoe doesn't fit me. I have only tried it on indoors since I obtained it. I purchased this item, which was being sold with the above description. I usually wear 29cm spikes, but I fell in love with the design and bought them. However, they were a little too small for me, so I am selling them. I have only tried them on indoors as well. This is a navy nubuck material that is not available in commercial products, and the metal fittings are still in good condition. This is a one-of-a-kind item that is not available in the market, so how about it for those who can wear it, those who want to collect it, or those who are interested?
