Rebound boots look like fun, and they are, but the real story is impact. The spring system absorbs up to 80 percent of landing shock, so knees and ankles take far less punishment than road running.
Start on grass. Flat, soft ground forgives wobbles while you learn the bounce. Ten minutes is plenty for week one.
Fit matters most. Straps should be snug over the shoe with no heel lift. If your foot slides, stop and re-fit before continuing.
Build gradually. Add five minutes a week up to 30. Alternate bounce days with walking or strength days while calves adapt.
Keep it upright. Tall posture, soft knees, eyes forward. The boots reward good form and punish slouching fast.
Done right, rebound training is one of the highest-calorie, lowest-impact cardio options you can do outdoors.
