This is the Best shoe for those of you who walk with a leaning gate to the outside or inside.  I bought my 1st pair 1-1/2 years ago at "If the Shoe Fits" next to the Barbara Fritchie Restaurant in Frederick, MD on the Golden Mile.  This is the Best Shoe Store I have ever been in, because they actually have you walk on a Treadmill to see your gate, & perform other tests to see how you walk & what the Best shoe would be for you.  Since I have Foot pain every day, I needed to fing the very BEST shoe to wear all the time, no matter if I'm at Church or at Work.  The Brooks Black Addiction Walker can be shoe polished to look like dress shoes on Sunday, but the best thing about this shoe is that it somehow straightens your Gate somewhat and helps you walk straight.  In fact, my wife just picked up a new pair from the store, size 10.5 2E width and I can compare the 2 shoe tread patterns which prove that these shoes do change your gate somewhat & enough to save your shoes tread for another 6 months. Also, they're not done being used, so I now have a working around the house pair and a new pair.  Now with Fibromyalgia this shoe will help you to get through the day better, but you will still have pain.  Study up for yourselves. I had to leave my last foot Doctor because they sell New Balance Shoes & made a imprint of my feet for an insert that was supposed to cure me of Plantaar Physilitis, except that the inserts hurt my feet so bad and my socks started sticking to them because my Gate was causing the top layer to slide off to the right side & were no longer usable.  No more Foot Doctors, & New balance are Great Shoes & I wore them for 15 years at about a pair of 602's or 608's a year @ $45 at the Shoe Dept. because they sell wide sizes, but they will not help to correct your gate or how the tread wears.  I believe that the Amazon.com decription tells you that there is a moving type of Silicon in the shoe sole for even balance and comfort.  Hope this helps you out like it did me.  You can find these shoes for $99.95 ~ $100.00 with Free Shipping & Free Returns from many online stores, so you can't lose.  This beats the store in Ellicott City, MD that wants you to buy their $250 shoes. Trust me, You can't go wrong with these shoes.
