Shoe selection depends on three basic conditions: the patient’s physical condition, the shape and characteristics of the foot, and the patient’s daily activities. For patients with no history of foot ulcers, no associated peripheral neuropathy, and normal foot structure, a commercial shoe with appropriate material and good comfort is sufficient; if the patient has neuropathy, a history of foot ulcers, Charcot’s arthropathy, or an amputated toe, more specific foot protection is required; when selecting shoes for patients with severe neuropathy, a shoe with a soft, malleable upper material should be selected, and there should be There should be enough space inside the shoe to accommodate traditional orthopedic braces. The shape and characteristics of the foot are also important for shoe selection, and the chosen shoe should be compatible with the structure of the foot. Larger patients should use solid, well-constructed shoes that do not break quickly, while smaller patients should use relatively lighter weight shoes. The shape and size of the foot is diverse, and so should be the shoes, of which the most critical issue is – the shoes chosen must fit the shape of the foot and its characteristics. In addition to a good fit, a properly fitting shoe should also have sufficient depth to accommodate additional supports (foot orthoses or ankle orthoses). In short, the shoe must match the type and shape of the foot. If the patient has extremely flexible flat feet, a shoe with firm support should be used; if the foot has hard calluses or bony prominences, a shoe with a soft sole should be used in order to absorb shock. The shape of a shoe depends on the sole, which comes in a variety of shapes, and manufacturers choose soles for specific applications, so a size 7 shoe made by company X will be significantly different from a size 7 shoe made by company Y. The size, shape and width of soles used for foot treatment vary, and may be tapered, round or square, in addition to inflare, outflare, long-toe or short-toe soles, in addition to soles that can be made into a joint type, such as a heel that is significantly narrower than the forefoot, allowing the forefoot enough room to move while ensuring the comfort of the hindfoot. In the toe and instep position, the depth of the shoe is very important and in principle should not create pressure in the above position. Generally speaking, shoes with laces or buckles are better than Slip-on shoes because the latter are tighter and shorter in design. The patient’s occupation, movement and the surrounding environmental factors also play a role in the choice of shoes. Certain special jobs require steel-toed safety shoes or safety boots, while certain jobs require formal dress shoes. Choosing the Right Fit After choosing the correct type of shoe, the next step is to decide on the proper size of the shoe. There are several devices that can be used to evaluate shoe size, with the Brannock device being the most complete, measuring the length of the full foot, the length of the arch (ankle to ball of foot) and the width. If the shoe is properly sized, the first metatarsophalangeal joint can comfortably land in the most spacious area of the shoe, which is the purpose of measuring the arch length. Foot measurements should be taken in both weight-bearing and non-weight-bearing conditions to understand the extent of change in foot shape and size in both situations. Also, both feet should be measured because most people have different sized feet and if this difference is significant, you are likely to end up with a pair of shoes that don’t look quite right. Foot measurements are taken by any method in order to know the size of the foot, however, the result is not necessarily the size of the shoe. It is also necessary for the orthopedist to have a good understanding of each shoe, how each shoe fits, how each shoe size matches the foot size, and the characteristics of each shoe’s fit.
