Q: [header] How to walk for exercise at night [title] Get some comfortable shoes. [step] Although you can walk in other kinds of shoes, a good pair of sneakers can help to make your evening walks more comfortable. A good pair of walking shoes will provide adequate levels of lift in the arch, as well as ankle support. <sep> (A) [substeps] Make sure that the shoe that you chose is made from strong leather and should not be torn to pieces. Footwear made from a solid-soled, or semi-flexible, durable material does not make good sneakers. (B) Choose wedge style shoes, with shorter toe lengths, for people with mobility issues, who can easily walk across the street. [substeps] Keep in mind that support isn't always directed specifically towards your feet. (C) [substeps] Your shoes should be very comfortable to put them on.

[substeps] If you already have a pair of shoes you enjoy walking about in, then you can just keep wearing them.
