There are not many choices when looking for a pair of neutral walking shoes that also come in wide sizes and are roomy enough to accommodate orthotics.  Enter the 577.  Enter the comfort zone. Not only are these shoes great for walking and general use, they make my feet forget they have shoes on. I am also a big fan of the sl-2 shoe last that this style is built on. As for size, I order the same as for my New Balance running shoes. Six months of wearing the 577's has convinced me that this is the shoe for me.
