We are both not overly hard on the legs / calves, but get the zippers only halfway to. From the top-mounted pushbutton times to mention. Question really as thin legs you have to have me to fit in there. The material, however, and the attached outsole seem quite good and stable.
An absolute bad buy. Because us the return procedure is simply too annoying (attached declaration on how to "make easily in 5 steps" that) is, unfortunately kicked out the money. Too Bad.
