I recently bought a pair of Nike Vomero +8s to train in. They were working really nicely until yesterday and it seems like they've either been rubbing on the top of my foot or something because I have a red bump on my foot now that feels irritated when I put the shoes on. I don't feel it while I'm running, but when I put on my shoes I do. Does this mean get new shoes, or is there another way to solve this?
