All my shoes were 9.5 but even after 1 week of daily wear I still have pain. Obviously the seller doesn't want you to return them once you've worn them. However, no shoe fits perfectly on the first day. I have contacted the seller and will contact Best Buy customer service if any changes are made. I will update the rating if there is not a single star all day. No vendor update expected. I contacted Best Buy and Best Buy contacted the seller, now we are waiting for the seller. My nightmare continues.
