Study Arms:
- Intervention Group (Type: EXPERIMENTAL): Daily use of the intervention Flexible footwear (Moleca®) for 6 months, for at least 42 hours/week (approximately 6 hours/day, 7 days/week). The Moleca® shoe (Calçados Beira Rio S.A., Novo Hamburgo, Rio Grande do Sul, Brazil) is a low-cost women's double canvas, flexible, flat, walking shoe without heels, with a 5-mm anti-slip rubber sole and a 3-mm flat insole of ethylene vinyl acetate that provides only protection but no correction. The mean weight of the shoe is 0.172±0.019 kg (range 0.091 to 0.182 kg), depending on size. This minimalist footwear is commonly worn by the elderly of all social classes and its average cost is US$ 6.25.
- Control Group (Type: NO_INTERVENTION): During the intervention period, patients from the Control Group (CG) were instructed not to wear Flexible footwear (Moleca®) or other similar minimalist footwear. During everyday activities, the CG group was only permitted to wear a standard, neutral tennis shoe. At the end of the intervention period, all CG participants also received one pair of Moleca® shoes at no cost.
