I bought them a year ago for work boots, because my job requires a lot of standing, and although they were very comfortable because they had reinforced arch support and air cushions in the back that absorbed shocks, in less than 6 months the air cushions started to fall off and the padding as well, and after 9 months the air cushions have lost all their air and not only do they not provide any cushioning, but they also "puncture" the heel with the vertical cylindrical supports they have. So yes, they are comfortable, but they have little durability over time and with such a high cost they are not worth it. Finally, they increase the height of the shoe due to their thickness (which is logical in order to provide cushioning). They cannot be compared to a good shoe in terms of cushioning and comfort obviously.
