I used it for the installation of the calle on the existing legal aspect. First of all, from the conclusion it is a product that can be used. (It is rude to developers ...) There was not something like a gap if you tighten the adjustment band tightly and use it. However, since the ankle which can be fixed is fixed, there is an impression that it is hard to move. Since it will be necessary items when working on the legal side, I would like to improve under the assumption that the feet will move as much as possible. It is because the orientation of the foot and the way the load is applied tend to be irregular as a matter of fact on the slope work than the work on the flat ground. However, I tried using it for a week but it was never out of the boots and I went up and down the ground with normal shoes, but I had a sense of security and it was good.
The spike part and its base are robust and secure. Also, the belt has a notch that can be tightened up and can be tightened finely. It is regrettable that there is a part where the wire part connecting the belt and the base of the spike is insufficient and has come off.
