I bought this pair of Asics (White/Red/Turquoise) in size 7.5 at my local sporting store. (I normally wear size 7.5)

I wear this pair primarily for the kickbox cardio class I am taking.  I needed a pair of shoes that has more cushion than some other running shoes they have out there, a pair of shoes that kind of hold my feet in place for balance when I am kicking with my feet during my exercise.  I have tried on Gel-Cumulus 11 & 12 in the store, but I found Gel-Cumulus 13 has more of "cushiony" feel to my feet when I jump up and down than the other lines of Gel-Cumulus, it is as if Gel-Cumulus 13 pair has more "shock" absorbancy, if that makes sense. This pair of shoes also feels light on my feet.

For some people, this pair might feel kind of tight, my recommendation is to wear thinner socks or go 0.5 size higher, depending on what you will be wearing this pair of shoes for (casually, running errands, running, walking, etc).  In my opinion, it's best if you can try this pair on at your local sporting stores to ensure the accurate size that works you, you can then order via Amazon to save few bucks.

Oh, silly reason for deducting one star: I didn't like the turquoise color on the shoes. :P
