Do not use old shoes for big run

I had the show with over 1600 (1000 miles) km of mileage. I tried doing 10 miler on it. I faced the biggest pain in my leg and hips. It was a nightmare. I had to rub iodex and could not walk better for many days. I had a great learning that a serious runner should not use the same show for more than 600 miles. If to be used the old shoe, we should not use it bigger runs or tempo run.
