Barefoot shoes have to be wide so your toes have optimal movement. If shoes are too tight, the toes cannot move properly and the muscles are restricted. At first, your ‘proprioception’ (your awareness of your body movement) often makes it feel like a barefoot shoe is too big. We are so used to wearing tight, narrow shoes and are also used to wearing shoes that are too small. People with a flat foot arch should choose a smaller size. A lace-up shoe is better than a slip-on or ballerina shoe. Often, a slightly higher shoe upper also helps as this can fit better due to the additional height of the upper. However, if the eyelets virtually "overlap" it often helps to reduce some of the shoe’s volume. This can also be achieved by wearing slightly thicker socks or an insole to position your foot a little higher in the shoe and fill the shoe better.
