Thank you for your interest in the product. 【Product Description】 - Brand: NIKE Nike - Model Name: Vaporfly Next% 4 - Size: 28cm 【Condition】 Only tried on indoors. I will send you a brand new, unused item. 【Other】 Instant purchase is OK. The item is in hand. I can ship it immediately. My impression after trying them on is that they are stiffer than the Adios Pro 4 and Alphafly 3. They don't have any strange quirks and are easy to control. I don't think your legs will give out during a full marathon. *I am around the sub-elite level. I will adjust the price while monitoring the situation. No price reduction.
