I generally don't wear cordovan boots in the summer, largely because it doesn't fit the wardrobe and there are better alternatives for me. Friday through Sunday from May-September in NYC, I'd rather be wearing LHS (cordovan, CXL or suede), suede longwings and shortwings, suede chukkas and PTBs, etc. Yukueten and Quoddy have great mocs available as well. I basically box up all my cordovan boots starting in May. I will keep CXL indy boots out for wet weather.
