Rally is an updated version of Gola's iconic Mark Cox style.  It is an entirely vegan product.  Its bumper and heel cup has is gum sole.  The upper is canvas and it has towel lining, which is so comfy.    Gola sizing is listed in US/Euro sizes as in 37/US6, 38/US7 and so on.  It is listed for our sizing purposes in US sizing.  We find that if you plan to wear them with a sock, they fit true to size.  Consider sizing down if you prefer to wear your sneakers with bare feet.
