These may be the most comfortable shoes I've ever owned!  I now have them in 3 different colors and use them for my Silver Sneakers exercise classes.  They run true to length and width and the innersole provides ample arch support.  After being so impressed with these shoes I decided to go for it and order the pink ones.  Be aware that they are really BRIGHT pink.  Also, the color which looks like medium blue in the photos and is called Oceans Depth looks more like a dark green in person.  I put them on and felt like I might as well be wearing a sign that said "Hey!  Look at my giant feet!"  So, I returned them.  But, if you are looking for something bright and cheery and don't mind having attention drawn to your feet, then you might like the pink ones because this style is truly comfortable.  Some reviews have complained about rocks getting stuck in the soles.  I have not had that problem.  I don't run on any trails.  But the open parts of the sole certainly do make for a cooler athletic shoe.
