Sea anchor

A sea anchor (also known as a drift anchor, drift sock, para-anchor or boat brake) is a device that is streamed from a boat in heavy weather. Its purpose is to stabilize the vessel and to limit progress through the water. Rather than tethering the boat to the seabed with a conventional anchor, a sea anchor provides drag, thereby acting as a brake. ...

Are Shock Absorbing Shoes a Waste of Money? | Breaking Muscle

The study examined data from 18 studies: seven that involved shock-absorbing insoles, and 11 involving shoe orthotics. Of the seven studies, none proved that shock-absorbing insoles actually helped to reduce the risk of injury. In fact, one study discovered that shock absorbers increased injury risk.. With orthotics, however, there was some visible reduction of injury risk.
