The shoes seem to fit about 1/2 size larger than other similar athletic shoes. I was not impressed with the results. Wore the shoes for about 10 days at the recommended breakin time each day. All the results were less than positive. My back and neck were sore all the time, and I did not feel any aerobic differences. Had I given the shoes a longer test perior, I don't know if I would still be walking. Not for me.<a data-hook="product-link-linked" class="a-link-normal" href="/Skechers-Men-s-Shape-Ups-Lace-Up/dp/B001U0OQ6S/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Skechers Men's Shape Ups Lace-Up</a>
