Your shoes should be neither too tight nor too loose.  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.  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. Try on shoes before you buy them, even if you know your size. This is because sizing may vary widely from brand to brand. Purchase shoes that fit well, even if the size is different from what you are used to wearing. Feet may swell up to eight percent in the course of the day, so shop for shoes in the afternoon, as that is the time of day when your feet will be enlarged. By choosing shoes that will fit comfortably even when your feet are at their largest, you will help to prevent blisters at all times. Shoes that squeeze your foot, ones that are too loose, or ones that cause you to walk abnormally subject your foot to pressure and friction that may result in blisters. Try to avoid wearing these types of shoes, which include:  High heeled shoes, especially those with narrow toe boxes. These can force the toes into a cramped position, put intense pressure on the ball of the foot, and increase friction on the heel and elsewhere. Flip-flops, which put pressure on the toes as they squeeze to keep the shoes from falling off. Any overly tight style of shoe. Before wearing new shoes for prolonged periods of time, wear them for just short sessions. For instance, before wearing a new pair of shoes all day long, wear them for just a couple of hours at home. This process, known as breaking in your shoes, gives them time to gradually conform to your exact foot shape so that they will fit most comfortably. It is especially important that shoes which will be worn for athletic or intensive purposes, such as hiking boots, are properly broken in before they are used normally. Cotton socks can absorb moisture; this can help control foot odor, but friction caused by the damp cloth also increases the risk of blisters. Instead, choose socks made of quick-drying synthetic fabrics or wool.  Padded sports and hiking socks can be found at athletics and footwear stores. These can help prevent blisters. Some people prefer to wear two layers of socks to combat moisture and friction: a thin “wicking” sock and a thicker sock over that. At footwear stores and many pharmacies, you will be able to find a variety of insoles that can be inserted in your shoe to provide more support, comfort, and a better overall fit.  Make sure to purchase shoes with removable insoles so that you can replace them with more comfortable and/or supportive insoles as required.  Replacement insoles may be made of neoprene (foam rubber), memory foam, gel-filled pads, and other materials. Evidence shows that neoprene insoles in particular can reduce the incidence of blisters.  Insoles, especially orthopedic ones, may be available in various shapes designed to conform to different foot types. Try out different insoles until you find ones that fits your shoe and foot comfortably. For instance, don’t wear the same pair several days in a row; instead, alternate them with another pair or two. By wearing different shoes, you will help to prevent blisters by ensuring that your feet aren’t always being rubbed in the same places. Choose shoes made of material that is watertight but also breathable. This will keep moisture out, but also allow sweat to evaporate from your feet.  Plastic and nylon shoes make it hard for your feet to ventilate. Choose footwear made of leather, canvas, mesh and other breathable materials. If your shoes or socks become wet, remove them as soon as possible. Let them dry before wearing them again. Dry your feet and put on fresh, dry socks and shoes.
