Most modern-day shoes are designed to be “put on and go” meaning there is no need to break them in, but you might need a transition period because you’re switching shoes. Start easy when using the shoes. The best times are Christmas, black Friday and the end of June and start of July because they have clearance sales. It is cheaper to buy 2 identical pairs of shoes because you can switch them out and they wear out less often. Also save the specific shoes for the specific event. Ex:Basketball shoes for just basketball, running shoes for just running etc.
