I bought a pair of Umbro x300 boots (got them for $35 and using them for a practice boot) and basically walked around the house with them for a day. Today was the first day I used them out on the pitch, but I was experiencing pain on the bottom of my foot, more so the arch. From what I can rememer, this happened to me when I was breaking in my Cellerator Zero 5s a few years ago, but after that I was fine. I'm not exactly sure if the shoe doesn't fit my foot well - like I said, it's happened to me before, but eventually I was fine when I broke it in. Anyways, just out of curiousity, does anyone get any similar pain when breaking in a new boot?
