I'm 37, I have always done fitness (running) on and off for many years. I use to find when running on a tread mill with "running" shoes I would get pins and needles in my toes - both feet. I tried changing the incline and resistance - nothing worked For the past year I have been running on the tread mill in flat walking shoes and had no pins and needles. Recently, thinking I should get a "proper" pair of shoes for the rest of my body's sake I bought a good pair of "running" shoes. Now, I have the pins and needles again...in proper shoes. My ankles, shins and feet were starting to feel a little abused from the walking shoes so I assumed a "running shoe" should be what I was using. Now I have the pins and needles. Socks are lose and breathable, shoe is not tight. Any ideas ?
