Compression, sculpting, support — the category leans on these words, and almost none of them are measured. We do not use them, because we have not tested them and cannot show you a number behind them.
What we can tell you is on every product page: the fibre content where the mill states it, the construction, the fit as it is described to us, and nothing beyond that. If a claim is missing here, it is because we could not stand it up.
