I'm using the Gravity Boots on a chin-up bar, this is mounted on the ceiling. The boots are a little too big but that due to the good padding is not a problem. I wanted with this product have another option for abdominal training. This' '' upside down '' situps thus fulfill my expectations fully ..
Qualitatively, I think these boots are very high quality, I am afraid at any time the material could give way and everything keeps 1A. (I am 1.80m / 80kg).
But quality comes at a price, a fairly high in this case. Therefore, a star deduction for the price.
