The sole of the shoe must be both rigid enough to prevent bending when you press firmly on the toe or heel and flexible enough to provide good walking traction. Last but not least, the hug of the shoe is the factor you need to know. When lifting large objects, the foot should not expand out, thus shoes must fit tightly against the foot. If required, you might add a cushion to the foot's sole to improve the shoe's grip. This keeps you cozy while traveling. https://outdoorgearreviews.org/best-walking-shoes-for-men/
