What factors apply to proper footwear?

Proper footwear should provide adequate support, cushioning, and stability to promote comfort and prevent injuries. The fit is crucial; shoes should be neither too tight nor too loose, allowing for natural movement of the feet. Additionally, the material and construction should be suitable for the intended activity, whether it's walking, running, or working. Finally, consider the terrain and weather conditions, as these can influence the choice of footwear.
