Teeter Hang Ups EP-550 Sport™ with Gravity Boots is all the EP-550 features with a couple of items more:

For a more intense inversion experience and greater versatility, consider the EP-550 Sport™! Includes all the features of the EP-550™, plus an adapter kit with gravity boots for greater ankle support on the inversion table and added comfort during inverted exercises. Also added are the EZ Stretch™ Traction Handles to increase your stretch during the inversion and also help you get back up from a full inversion.
This is a great move providing a sport model since it makes hanging upside down a lot more bearable. People often complain about ankle pain caused by inversion, however some discomfort is to be expected because our bodies are not made to be hung by our ankles. The boot kit makes inversion much more tolerable than traditional methods and enable a comfortable hang for a half hour or longer in them. If you have bad ankles however look into waist supported inversion elsewhere on this site (not as effective, but much easier on the knees and ankles). If your joints can take a little beating, this is the best your gonna get!
However, not everyone is appreciative of this sport version kit, I have seen at least one person complain that perhaps the traction handle is not that useful for the price charged and recommend buying the regular EP-550 and the gravity boots kit separately and save money on the traction handle. If you really want to try the traction handle, just buy it separately as there doesn’t seem to be any discount for buying the EP-550 Sport.
A note on storage: the unit easily breaks down into two parts by lifting the table off the frame by simply sliding 2 spring loaded retainer clips with your fingers. The table is 32.5 pounds and the base 27.5 pounds for a total combined weight of 60 pounds. It is a bit cumbersome and heavy to move as one unit. When you pull the table off it is much easier to move the two individual pieces. Downside if you have to put it away on a regular basis: with the table attached to the base it does not fold up into a very compact unit. You can store it in less space by removing the table from the base. Although for people with a bad back the table at 32.5 pounds could be too heavy to lift on and off the base.
Unique to the Sport Option:
Gravity Boots: Use your Gravity Boots with the table or take them to the gym; great for inverted sit-ups and squats. The Gravity Boots wrap comfortably around each ankle, securing with adjustable, self-locking ratchet buckles. Super-soft 5/8″ foam liners are a special blend to give maximum comfort with minimum compression. Made of light, highly durable DuPontT HytrelT material for a comfortable fit.
EZ StretchTM Traction Handles: With the muscles in your lower back relaxed, pushing on the handles can help to increase traction and enhance your stretching experience. The handles can also be used as a tool for intermittent traction and oscillation.
