Query: Quality of shoe

I have used Saucony shoes for years. In fact one of my favorite running shoes 25 years ago was the Saucony Jazz.As to the recent purchase. I was pleased that Amazon made possible the purchase of Saucony shoes. BUT after using them for a short time I realized they were defective. I noticed that the ball of my foot was dropping into a depression which caused my foot to become very sore. When inspecting the shoe closely the slope and placement of the raised treads on the bottom of the shoe and the relative thinness of the inner removable sole were allowing the ball of my foot to drop into a hole which was rubbing and creating soreness. I have partially corrected this by placing a thick piece of doe skin on the bottom of the inner sole. The situation is still not right.thanks for listening Karl Mosher
