The first time i missed with the size-my 37-37,5, but 38 size was small, but it perfectly suited my mother with 36 foot size)
For my leg perfectly fit 39. So i recommend choosing 2 sizes larger.
Especially they will be useful for people with flat feet. If there is no flat foot, the internal arch of the foot will not be massaged. But you can separately pump, standing across the sneakers.
Made soundly. Sole made of wood, pleasantly smells of juniper (maybe special impregnation)
Of the minuses. It's more like hell perfectionist. One sneaker is perfect, on the second one stone is strongly crooked glued, and on the foamed part of the sole scratch.
But this does not affect their good functionality. So you can forgive some negligence)
