Bought these looking for a way to relief some back pain (L3-L4 bulge) and boy it does sure work.
Initally its very odd hanging upside down, so i fully recomend using the strap sent with the boots to help you up. Tie it on the bar and hold on to it.
Start slowly and build up. Im up to 10 sets of 1 min everyday. Feels amazing.
Product is affordable and well built, feels very secure. Im around 100kg btw.
Tends to slide a little if you are too sweaty (which is normal) so i recommend using some shoesw while on it, otherwise you may feel a bit too much pressure on the ankle.
10/10 product, totally recomend
