After reading reviews and being a fan of Saucony I switched from my discontinued Guide 5 (8mm drop) to the Kinvara 3. Reviewers suggested going up one size which I did. It was not necessary. The second pair I bought was my regular size and I like the fit much better. Being a minimal running shoe I suggest you buy good running socks! I use my shoes for about 400 miles (only for running) then retire them for a new pair. Buying them on Amazon saved me money, I got them quickly and am pleased.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Saucony-Men-s-Progrid-Kinvara-3-Running-Shoe/dp/B006MQPGCS/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Saucony Men's Progrid Kinvara 3 Running Shoe</a>
