I just tried the Saucony Endorphin Pro 3 at a marathon, had painful hotspot throbbing in the ball of my foot for the last 10 miles. While I’ve run with many different shoes and never had this much pain, I think the rigidity of the shoe and carbon fiber plate didn’t provide enough cushioning for my arch. Any recommendations for a racing alternative to carbon plated shoes? I’m also trying out high arch insoles so the door is wide open for different shoes to try right now.
