I recently purchased a pair of these, http://www.vans.co.uk/uk-en/old-skool-mte-shoes.html perfect for flats and straps, i find that vans old skools are probably the best for riding flats and especially the ones in the link for cold wet weather riding, has a thermal lining, water replant coating and vulcanised lug out soles which offers better grip than regular vans.
