These look legit and authentic 100% right? What about the price, do you think I could do better to wait? These would be a Lanvin size 8? http://cgi.ebay.com/Lanvin-Mens-Snea...ht_3968wt_1141 Secondly, sorry, just verifying with the size after looking at the size chart, so does this mean it fits 1.5 sizes bigger than the Lanvin size, or 1.5 sizes bigger than the US size? Ex-Does a Lanvin 8 fit a 9.5 or 10.5 US? Might want to clarify that on the size chart.
