Today I went to the beach, and was reminded of the benefits of walking barefoot on the sand. Not only does it feel great on your feet and you get a bonus exfoliation, but the instability of dry sand makes your feet and calf muscles work harder, building strength and burning kilojoules. If you get tired, walk on wet sand, which is easier (and cooler!)
Do you walk barefoot on the sand much?
