Itching to get your kick on? Loathsome to some, a savior to others. And of course, a lot of swimmers will pull from the flags into the walls when doing kick , negating large chunks of their kick work.

Thickness and sturdiness are the two biggies with this kind of kickboard—a flimsy and thin kickboard means you have little buoyancy, with the board dipping below the surface of the water.
