These shoes are really great.  This is actually my second pair of Gel-Spree because I loved my first pair so much.  I was going to NYC so I needed a new pair of good yet comfortable, light walking shoes and these did the trick.  Let me tell you I put them through hell on the trip and they are still good as new!  I was very impressed that even in NYC the white part still looked white.
It is a very light-weight shoe with a nice flexible sole so they are good for walking or light exercise.  The outer sole is not too thin nor too thick and the style is sleek, which is good since I'm slightly clumsy but I've never tripped myself with these.  The inner sole is flexible and firm, not "cushiony", but very comfortable for walking.  Sometimes if the inner sole is too firm I need inserts but not with these.  They are also good for everyday use since the dark color is stylish but subtle with just a small pop of pink so it doesn't look too obviously like an athletic sneaker.
My only issue is that my first pair got a hole worn through from the mesh upper part on the outer side of both shoes!  I usually wear out shoes from the toes not the sides.  I hope this pair turns out to be more durable, but its a bit disappointing that the upper wears out long before the sole does!
