Flowfeet is compatible with feet ranging from shoe size 36 to 47. However, it's worth noting that we have tested and sold Flowfeet to individuals with shoe sizes larger than 47. This variation is due to the differences in foot shapes, including width and height. Since Flowfeet utilizes airbags that adjust their pressure according to the foot's shape, it can accommodate sizes larger or smaller than the specified range.
