These are often referred to as essential joints. A few of the joints are quite mobile and are required for the foot to function normally from a biomechanical point of view. It is helpful to think of the joints of the foot based on their mobility (Table 1). ![]() Where two bones meet a joint is formed –often supported by strong ligaments. The foot is comprised of 28 bones (Figure 1). There are two sesamoid bones embedded in the flexor hallucis brevis tendons that sit under the first metatarsal at the level of the great toe joint (1st metatarsophalangeal joint). The great toe has only a proximal and distal phalanx, but the four lesser toes each have proximal, middle, and distal phalanges, which are much small than those of the great toe. There are twenty-one bones in the forefoot: five metatarsals, fourteen phalanges, and two sesamoids. The bones that make up the forefoot are those that are last to leave the ground during walking. The Forefoot is composed of the metatarsals, phalanges, and sesamoids. The five bones of the midfoot comprise the navicular, cuboid, and the three cuneiforms (medial, middle, and lateral). While the midfoot has several more joints than the hindfoot, these joints have limited mobility. The Midfoot begins at the transverse tarsal joint and ends where the metatarsals begin -at the tarsometatarsal (TMT) joint. The bones of the hindfoot are the talus and the calcaneus. The Hindfoot begins at the ankle joint and stops at the transverse tarsal joint (a combination of the talonavicular and calcaneal-cuboid joints). Additionally, the lower leg often refers to the area between the knee and the ankle and this area is critical to the functioning of the foot. The foot is traditionally divided into three regions: the hindfoot, the midfoot, and the forefoot (Figure 2). These will be reviewed in the sections of this chapter. There are a variety of anatomical structures that make up the anatomy of the foot and ankle (Figure 1) including bones, joints, ligaments, muscles, tendons, and nerves. With a good grasp of foot anatomy it readily becomes apparent which surgical approaches can be used to access various areas of the foot and ankle. For those conditions that require surgery a detailed understanding of anatomy is critical to ensure that the procedure is performed efficiently and without injuring any important structures. Therefore a basic understanding of surface anatomy allows the clinician to quickly establish the diagnosis or at least narrow the differential diagnosis. ![]() Anatomical structures (tendons, bones, joints, etc) tend to hurt exactly where they are injured or inflamed. Most structures in the foot are fairly superficial and can be easily palpated. Nike Flyknit, for example, is a lightweight fabric precision-engineered with an average of 60 percent less waste than in traditional footwear upper manufacturing.Īnd Nike Flyleather, while it looks, feels and smells like natural leather, is made by binding at least 50 percent recycled leather fibers with synthetic fibers using a water-powered process, ultimately creating less waste and a lower impact on climate change compared to full grain leather.A solid understanding of anatomy is essential to effectively diagnose and treat patients with foot and ankle problems. Exploring shoes made sustainably can give you a comfortable upper, with fabrics made from sustainable materials that have proven their worth when it comes to sneakers. When it comes to the upper part of your shoe, look for sneakers made from soft, breathable materials for added comfort. You may sometimes feel like it’s that pesky piece you’ve got to pull up each time you get your shoe on, but it actually protects the top of your foot and prevents the laces from rubbing. The top of your shoe is also made up of the quarter, which is the area covering the sides and back of the foot, and the tongue, which plays a very important role. The eyelets are the hole the laces go through, and the eyestay is the material that holds the eyelets in place. Other elements include the eyelets and eyestay, which work together to hold the laces. ![]() Think about the pop of color that neon laces can bring to your look. Laces, for example, are a necessary component when it comes to fit, but they also contribute to the style of the shoe. While all the parts on the top of your shoe serve a particular function, many of them are also about style.
