Great advice.
And in the walking vein, good shoes are essential. If you can’t afford new shoes then good insoles are the next best thing and almost as good. Any aftermarket insoles are better than what comes with any shoe (and I mean any, that’s the thing they all cheap out on). You can buy what fits your foot (flat, medium, high arch) and they make walking painless.
