Due to changes in foot morphology and the occurrence of foot deformities and foot pain with ageing, older people frequently wear ill-fitting shoes. This can lead to discomfort and reduced mobility. A review of the literature was performed in Medline, Scopus and Embase with three aims: (a) to evaluate the effects of shoes or shoe elements on the comfort and mobility of older adults, (b) to summarise the evidencebased elements of a safe and comfortable shoe for older adults, and (c) from that, to compile those elements into design recommendations for a safe and comfortable shoe for older adults. Safe elements of footwear include proper anatomical fit, a well-fitting toe box, limited heel height, a broad enough heel, a firm insole and midsole, an outsole with sufficient tread, bevelled heel, firm heel counter with snug fit, and an easy and effective closing mechanism. We conclude that there is a need for shoe design specifically aimed at the foot morphology and demands of older people. The shoe market should increase the availability of well-fitting shoes designed for the older foot and person. 1.1. Morphological changes Changes in foot morphology occur with ageing, [2-7], and might differ between men and women [5]. Older adults have a lower medial foot arch but an increased circumference of the forefoot, ankle and instep [2]. For the same foot length, older men have larger foot parameters than women, including foot width, ball girth, upper arch, and toe depth [3]. Flat feet are more common in older women [8] and the first and fifth metatarsophalangeal angles are increased, which might be due to the higher prevalence of hallux valgus in women [4]. For older women, ball width, high instep circumference, and heel instep circumference also increase with age [5]. 1.2. Pain Many older adults are confronted with foot pain when wearing shoes [4,3,9-11]. This may be due to an increased prevalence of foot deformities, such as hallux valgus, mallet toes, hammer toes and claw toes [8]. Hallux valgus is related to the wearing of shoes with small toe boxes at age 20-39 years [12]. 1.3. Doffing and donning, i.e. getting in and out of shoes Ageing frequently leads to problems with doffing and donning, i.e. getting in and out of shoes [10]. Therefore, easy and effective closing mechanisms are usually preferred. 1.4. Ill-fitting shoes and safety aspects As a consequence of the afore-mentioned changes, older people often wear ill-fitting shoes [13,14] or resort to comfort shoes or slippers, especially in and around the home [9,10]. Unsafe or unsuitable shoes affect balance and gait, and might play
