For anyone who has foot problems the 990 V3 is a winner. To even make it better use the appropriate socks. I use loose acrylic socks do not tie laces tight and consider a better insole like the super feet ones. THESE ARE COMFORTABLE FOR ALL DAY WEAR.Since I OWN VARIOUS VERSIONS THERE ARE SLIGHT DIFFERENCE BUT ALL TERRIFIC SHOES. There maybe slight differences in stiffness/firmness but not enough to use them regularly.
