Input (English): [header] How to prevent foot blisters [title] Choose shoes that are the right size. [step] Your shoes should be neither too tight nor too loose. [substeps] A properly-fitting shoe will leave a half-inch of space between your longest toe (which is not necessarily your largest toe) and the tip of the shoe. <sep> (A) Because of the size of your blister, make sure that it is one that is soft enough to not cause pain or discomfort. [title] Fill your shoe with at least 100 millilin (household). (B) Thus, when wearing pumps or other high heels, choose shoes that are approximately two sizes larger than your ideal foot size. Bright, neon colors and type will also pair well with your shoe size. (C) Walk around in the shoes before buying them to ensure fit and comfort. A square or rounded " toe box " (the area of the shoe in which your toes go) will provide the best fit and greatest comfort. (D) Due to the size of your feet, you should try to ensure your shoes have no excess space between your toes, and therefore that they are as loose and comfortable as possible. Do not buy shoes with hooks or insoles, as your foot may be injured by these pieces of material.
