If you find that your trainers start to rub or your feet get cold quickly whilst out running, don’t automatically assume that it’s time for a new pair of trainers.  Think inside the box! Or shoe as the case maybe.  Could it be that you are wearing the wrong type of Running Socks ?  Ill fitting socks have been found to cause more problems that ill fitting trainers.  Wigwam are an American manufacturer of socks including a huge range of running socks.   Their socks repel moisture, help prevent blisters, are breathable and have a cushiony sold for comfort.  So instead of spending another fortune on trainers that you may not need try a different pair of running socks.
