Shopping for snug fitting gym shoes with the hopes of comfort – following break in period is the biggest fallacy. In fact, a 'break in' period is as authentic as the “Tooth Fairy.” So the question becomes – how does one shop for flexible fitness shoes without compromising style?

Gym shoes should feel comfortable from the first trial fit. Do not purchase show with the expectations of better fitting days.

Size alone is not the way to determine the comfort of a shoe. From manufacturer to manufacturer, shoe sizes vary. Try on shoes to feel how the gym shoe fits. Look at the width of the shoe and compare it to the width of your bare feet. Regardless how much you love the style of the gym shoe, if your foot appears wider than the object of your affection, do not buy the shoes.

Always try both shoes on for size – before finalizing your purchasing decision. For instance, certain individuals have one foot larger than the other. In situations like this, shoes that fit the largest foot should determine the most comfortable fit.
A minimum of a finger's width between your longest toe and the end of shoe is a good way to gauge a proper fitting gym shoe.

Go shopping in the late in the afternoon to early evening. Since the feet swell during the day, a gym shoe that feels comfortable in the morning may not fit the same way in the late afternoon hours.

Inquire about the online store's refund, exchange and return policy. Purchase several pairs of running, tennis or walking shoes. Try each on in your home for a several days. The vast majority of online stores and real world retailers allow shoe returns within a specified time frame. Obviously, the returns are contingent upon indications of wear.

Notice style, textures and materials. Select materials that allow flexibility to move, run and jump. Also, breathable materials are ideal such as nylon mesh or leather.
