I have extremely flat feet and have suffered from plantar fasciitis for many years. I began wearing the New Balance 991's about 8 years ago. These shoes immediately relieved my symptoms of painful arches, heels, shin splints when walking and running. I would replace these shoes about every 18 months. When they replaced the 991 with the 992 I had some reservations because I didn't know if they would change the product. The transition from the 991 to the 992 was seamless and I was able to wear these shoes pain free for many years. When my 992's were in need of replacement I ordered the 993's from Amazon without a second thought. These shoes hurt my feet from the first moment I put them on. The first pair I ordered was size 13D the same as all of the 900 series sneakers prior. They were too small to the point of hurting my feet when I put them on. My arches felt tension from the base of the shoe and the sides squeezed my feet. I put a 992 on one foot and a 993 on the other foot and they did not have the same feel at all. I was able to exchange the 13D for a 14D and I believed that this would solve my problems. I would continue to have pain while walking and running. I assumed that my foot problems were getting worse and went to my doctor. He told me to take some time off and the pains would go away. I went back to my running plan several weeks later after having no pain in my feet and I immediately started having problems. I stopped wearing these shoes and started wearing my old 992's and I was able to exercise pain free. I have since condemned these shoes to the bottom of my closet because they are either defective or poorly designed. I was able to purchase a pair of 992's from a website that sells discontinued new balance sneakers and I will probably order a second pair to get me through the next couple of years.
