I am 5' 6" tall and 135 lbs and fit.  I exercise for about an hour every day doing cross training and cardio.  I have purchased only Asics over the past five or six years but have found less and less to like about them.  A lack of stable options, wearing out too fast, and less quality in the sole.  I go through a pair of sneakers every three months so I want something that will hold up.  Also my foot rolls outward so stability is very important.  So is a decently wide toe box.  I wear an 8.5 women's in medium but my foot is on the wider side.

I have used these for about a week now and there is a lot to like.  They are lightweight and roomy on my foot.  They are very stable.  I don't feel any outward roll, but I also don't feel restricted.  While they don't feel squishy they are clearly well cushioned because i literally felt like i had a spring in my step - more energy - just walking around.  The first time i used them I did a 45 min walk/run on the treadmill and had no discomfort, pinching or cramping.  My foot that rolls out the most felt stable and comfortable.

The only thing i wish these sneakers had is an extra lace hole further down the top towards the ankle bone.  But some of that is because my other ones needed it since they were not as stable.  I don't feel the shoes are slipping i guess i am just so used to having to tighten them up to get them snug i keep looking for that set of holes.  It's not enough to make me want to return them.  I can definitely see me purchasing these again and exploring other shoes from this brand.

As a recommendation to others who mix running and walking with other types of cross training i suggest owning at least two pairs of every day exercise shoes and a third if you wear sneakers for around town.  I have a pair of Puma cross trainers that I use in the gym for classes and boxing.  These i use only for cardio work outs.  It makes a big difference to your feet to switch on and off and it greatly extends the life of the sneakers.  It's just like having different outfits for different events.
