RE...TALIAR... clothing, apparels, shoes, things have a screening, a calibration that is different in each country according to its origin metric, either decimal, in feet, inches, etc. RETALIAR in my opinion, is the activity of traders and industrialists to give parity or equivalence between a talla-calibre, according to various measures, where it shows is in footwear that is already the same pair, with different numbers so that the user chooses to linking the country with his own. The same shoe in China does not have the same number in America or Europe, RETALIAR, is carve re, highlight the size.
