&gt;Interesting, I haven&#x27;t heard of those.<p>Basically they improve blood circulation and prevent varicose vein problems.<p>My old coach was convinced it improved recovery time for lower-leg muscles after hard training and more or less made us swear to use them as much as possible :)<p>&gt;It&#x27;s funny, after you do it long enough your body craves it.<p>I&#x27;m doing daily (well at least 5-6 days a week) walks myself as well, I do between 50-70 minutes depending on how I feel, and yes it does become something of a craving, I typically feel uneasy if I don&#x27;t get out and walk.<p>The reason I started was as part of rehabilitation after a knee injury I sustained during sports, and it became a great habit (something good came out of that injury).<p>This might also play in to avoiding vein issues when standing since you get the leg circulation up and running during high pace walks.
