i hear you malat. i am just getting started, threw out all my old shoes. now i hve three pair of respectible shoes and my plans are to keep acquiring more and more. all thanks to this site!
Wow...your shoes went from 0 to 60 in impressive time...I have those G&G boots as well and love them. I like all your choices though. Only thing I'd maybe suggest is a closed-lacing black cap toe as a formal shoe if you need it for some occasions, but very nice collection.
That's definitely a nice chunk of change invested in shoes, but I'd say that money will lead to a bigger upgrade in look than money invested anywhere else in wardrobe. There's really no way to get nice looking shoes without paying good money for them.
