I love Suacony shoes and this was my second pair. The Omni series seems to have quality issues. I have ran between 200-250 miles on these shoes and they are torn from front as well as inside. My earlier Saucony lasted for over 350 miles as well as my Asics are currently about 400 miles. I don't run on concrete/asphalt. These were mainly used on treadmill. It's also weird that both left and right shoe were torn on exact same location.
