Bests & Worsts Reviews from Amazon

I know chucks have weird sizing, and so a women's 8 is a men's 6 and so forth, but the size chart given here is idiotic. There are literally about 50 different sizes listed in the item details, with M(D) and all sorts of other inscrutable nomenclature next to each size. Maybe this reseller should take a hint from the converse website which has SIZE/CONVERSE SIZE (women's 8/converse 6) so the customer can have a chance of ordering the right size.
