A dress sneaker differs from the usual brands with swooshes or three stripes in that they are usually monotone and without any brand logo or markings. Quite useful on dress down days when you are away from work. It also suits those who do not want to be mistaken for a rap artiste or an over aged teenager.
Converse basketball canvas sneakers are fine too as they are classics. But the dress sneaker is for days where a bit more style is desired.
