These shoes are awesome! This is my second pair, and I hope AVIA never stops making this style. I had a stress fracture on one foot and after two years of chronic pain I thought it would never heal. I started wearing these shoes and within a couple to three weeks I noticed my fracture no longer hurt and six months later my foot was completely healed. These shoes have excellent support and they force me to walk correctly (heel to toe). I also noticed my legs and glutes are firmer and leaner. I never had any problem balancing on these shoes and have never felt unstable no matter what activity I am involved in. I will wear these shoes as long as AVIA makes them!<a data-hook="product-link-linked" class="a-link-normal" href="/AVIA-Women-s-A9999-Avi-Motion-iTone-Toning-Shoe/dp/B002NKM4H2/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">AVIA Women's A9999 Avi Motion iTone Toning Shoe</a>
