My first Techamphibian (1) I have loved despite coming loose heel adjustment (the things have accompanied me on my way to SdC even the Cruze Ferro through the snow ...) Unfortunately, in two subsequent models supposedly improved heel setting has brought not really much, but dissolved now sewed at various points, the fit was not as usual. Inquiries at Salomon went unanswered. What he really did still: great grip in almost all situations (also tested for climbing) and light weight. Nevertheless, that was the last tech of Salomon, I ordered!
