I've been having a problem, so I'm stuck on the Yuna relationship going up after 4 hearts, I know that I need running shoes and I already done the event and talked to her, but I can't find them for the love of me, I've checked shop, I'm ran so much my stamina is nearly 1500 just to hope to God it'll show up in a vending machine, but no luck, what am I supposed to do? I got it on day 40, and I've spent the past few hours trying to figure it out (while also doing other tasks) and I'm now on day 72 and I don't know what to do
