Getting the wrong size. Different types of running shoes will fit differently. Always have your feet resized before assuming you know your shoe size. You might be surprised that a size 7 fits you in one brand, but an 8 is more comfortable in another. Selecting a pair of shoes solely based on looks. It’s easy to fall into the trap of choosing a pair of running shoes primarily based on their looks. Although you should find a pair you think looks great, you also want to make sure they perform well. Unfortunately, even if a pair of shoes look great on you, you might end up dealing with unnecessary pain and injuries if it doesn’t provide the proper support or cushioning for your feet. Forgetting to ask about discounts. Many running shoe stores offer special deals, but you may not get them unless you ask. Always ask if the store is running any specials before you buy. You might end up saving a few dollars! Not bringing your current gear with you. When you go shopping, bring your current running shoes, socks, and any inserts you prefer to use. That way, you can compare any new shoes you try on to your current running experience more accurately.
