I love a floaty midi dress - they can bury me in one - but trainers? Hot sweaty feet in some fugly clumpy trainers on a sunny day? Nah mate.
I agree - I live in NZ and while I think it looks lovely I can't stand the thought of wearing trainers, especially leather, in 30 degree heat. Sandals for me, or maybe canvas shoes if it's a bit cooler. Also, if your feet are on the large size white is not flattering.
