TONYKOAnti Gravity Inversion Boots for Stress Relief and Fitness

Small person need an extra sponge.

Probably won't work well with narrow legs. To start you might want extra padding, heavy sweats and sock. I used knotted rope to pull myself back up to bar.

These boots are well made and the extra safety device on the clasps is a welcome upgrade to my old boots. Unfortunately they cut off the circulation in my feet in approximately 1 minute of use and are painful to use. I bought them to replace my 90s era boots that were showing their age. With my old boots I could easily stay upside down for 3 min. or more. I tried these last night and I had to stop before 2 minutes because my feet were killing me. I'm not a large man 5'8 170 lbs., but these boots must be made for tiny and/or extremely skinny people. I'm hoping they will break in with use. Add-on: I realized after I wrote this review that the hooks are lower than on my previous boots. They were squeezing my feet between the foot wrest and the hook on bar on my inversion table. If I wear them without my sneakers they feel somewhat better but still not as comfortable as my old boots. The foam on these is softer and allow the metal part of the boot to angle up against my legs creating a pressure point.

I just received my Tonyko Inversion Gravity Boots this morning and was pleasantly surprised. The first thing that impressed me was the product was double boxed with another (sturdier) Amazon box. The original didn't look very sturdy. Nevertheless, my shipment made it to Alaska with no problems within 7 days.Upon unboxing the product, I noticed the boots were wrapped clear plastic and no documentation followed. As far as appearance goes, they look exactly like they do in the picture. The other main thing I noticed was the weight of the product, which pleased me. It was much heavier than I previously thought.The foamy part of the leg cushion feels like thick armaflex to me. It looks like its held on to the metal bands with adhesive only as far as I can tell. It seems to be forming a good bond to the locking metal band so I have no concerns there. The band and the hook feel as if they're both made out of steel. Not sure on the thickness, but judging by the weight and the fact that I can't bend it at all there's no doubt it's strong enough to hold my weight (180 lbs) no problem.The hinge that connects to two bands together is connected with three rivets on each side and folds smoothly back and forth evenly with no deviation. The latch looks like a draw type and locks down tight. Overall, I feel like this product is solidly put together.After inspecting the boots I felt really confident about putting them to the test. I read in another review that there was concern about the hooks coming off the bar because of the rounded part being fairly wide. For me, this wasn't a concern as I have a 1" diameter pull up bar. If anything though, I am going to keep an eye on this. I noticed that when I do an inverted sit-up it's best to keep my body stationary and make a controlled movement to the up position. Personally, it just seems like bad form to not do that as well.One last thing. After a few inverted sit-ups I noticed something. I was barely able to get back to the start position to lift the boots off the bar. I forget to mention that they do include a little strap in the box. Maybe it has something to do with this, I don't know, because their wasn't any documentation provided with mine. One thing that I thought about doing is using my dog's leash to throw around the bar to pull myself back up. Or you might also use it as a safety that you could attach to a riggers belt.Update 9/23/17: A few things. The dog leash and the riggers belt is unnecessary in my opinion. These boots have held up fine, but it's worth being sure not to handle/use them roughly either. I wear leg socks with mine to protect the foam and also make sure not to scrape them on anything because the foam can/will tear. To stop the back/forth swinging while inverted just touch the ground/wall/etc. and catch yourself. Do your repetitions slow and controlled and keep your lower body steady as to avoid movement of the hooks on the bar.5/5 stars.

These are well made and did make my back feel better after using them to hang. I expect replace them with a better version eventually. My two gripes are this:1) Not adjustable. They are just a bit big for my ankles, wish I could tighten them.2) They hurt the top of my feet, partly because they’re not adjustable and partly because the cushioning is so-so. Maybe as I use them more my feet will get used to it. But because they’re a little big, it feels like I have to point my toes upward really hard or else it’s even more uncomfortable. I was expecting my body weight would be suspended by my calves or ankles, but it’s not - it’s suspended by the tops of my feet. Something to keep in mind.For those reasons on day 1 I was only able to do sets of 60s, maybe one set of 90s.Also recommend getting a much heavier duty strap than what comes with the boots. The strap that comes with is better than nothing, a rope or thicker webbing makes pulling yourself up much easier.

I've had these about 2 months and my teenage son and I each use them 4-5 times per week - so they've had at least 50 hangs - they work well. He's 230lbs and they support him with no problem. There was an inversion table at my old gym and I liked it. I don't have room for that at home but I do have a pullup bar and these do the trick.Thick cushion protects my ankles well and once you convince your brain that your feet won't slide out of the boot, you can relax and get the stretch. It took me a few days to figure out how to mount the bar - I needed my son to help me for the first week or so - but once I got my technique down, it's easy. (PS: It's not about abs, it's about technique - tell yourself you're going to hook your knees over the bar and you'll get there). Comes with a strap to dangle from the bar to pull yourself up and dismount. Definitely hang that strap the first time. I don't need it anymore but I sure did need it the first few times. Dismounting IS about ab strength. I ALMOST took one star away because the latch bent on me the second time I used it. Might have been my fault - the first few times I used the boots I put them on a few inches above my ankle. TIGHT FIT. Too tight, and when I tried to snap the latch shut it bent. Now the safety catch won't engage. You don't need the safety if you wear them with the latch facing out. Now I put them on all the way down - almost touching the top of my foot and they close smoothly.Overall a great product for the price and worth getting if you want to spend a few minutes inverted after your workout.
