I Tried Therabody's New RecoveryAir JetBoots, and I'm Never Getting Off the Couch

After fully charging both RecoveryAir JetBoots, the battery lasts for 240 minutes — that's four hours! That means you can charge them before taking them to the gym, on a day trip to ski or mountain bike, or if you're going taking a car trip. Or if you're with a group of people, you can all have a turn without having ton charge them. The display on the front of each boot indicates how much battery life you have left. If you do run out of juice, you can still use them while they're plugged in.
