I need to buy a new pair of shoes but seem to be chasing my own tail. I have one pair of AE bay fields in dark brown that I adore. However, I am about to get a new job that is ok with business casual dress. I have a pair of black oxfords that will probably be sufficient to get me through the few rare occasions I would need them. But I'd like to add a shoe to the collection. I was thinking black shell penny loafer since I mainly wear khakis and odd trousers. Or a black plain toe slip on. If you go to the Aldenonmadison website you will see the two shoes I am considering. My requirements are mainly a shoes I can wear from jeans to odd trousers and maybe suits. Made from shell. I'd consider lace up shoes and boots but am leaning towards a slip on. Thanks for your help.
