I was wearing Dansko professionals but wanted something a tad dressier for work so I tried these in black first and loved them so much I bought them in each color.  I wear them every day, with suits, skirts, jeans, everything.  The straps are stretch enough to keep my feet in but loose enough so they don't bother me.  I have wide feet and I have bunions so I need a large toe box and these are perfect for me.  I can wear them all day without any problems.  I wish they made them in more colors/fabrics!!
