I usually wear one of my numerous $250 MBT shoes so I will be comparing this shoe to that quality of shoe and I will have to say that I love this shoe and it holds its own against my MBTs!  First of all, the main thing I look for is shock absorption because I enjoy walking often and want the comfort of feeling like I am walking on clouds without shock on my skeletal system.  These shoes are just as effective at shock absorption as my MBTs.  The quality of material that is in the sole is very good.  These shoes also do a great job of supporting my high instep so I kind of wonder about the review that says it is great for flat feet.  These shoes don't appear as expensive as my $250 MBTs but they look worth every bit of the full retail on Reebok Women's Simplytone Fitness shoe.  I got mine at Nordstrom rack for $69.99 plus CA tax less $25coupon and I am wearing mine often.

Also, these strengthen different muscles than the MBT rocking technology which mainly raises my "bottom line" (pun).  The Reebok Simplytone seems to isolate/activate my upper adductors (inner thigh) and abductors (outer thigh) as well as my hamstrings above the knee while they seem to help stretch and relax my calf muscles.  I don't know if that is what Reebok was aiming for but every woman is different and walks differently and I like how these work for me.

I highly recommend and am getting ready to order some from Amazon!
