Cabello EG1520 in a Jet Black is the ideal leather sneaker that would be perfect for work. A lace and zip fastener combination that makes life easier. Once the lace is done up to fit the zip would be the only thing you would have to fastener your shoe with. 

There aren't many black soled leather sneakers around.  These Cabello shoes are made in Turkey from Kid leathers so softness and cushion is what you feet will feel all day.
