Subject: RE: SBR Endurance Group - CLOSEDkimmax - 2012-03-15 1:43 PM Question for the group? How many km/miles on your runners before you replace them? I think I just zoned in on the reason for all my leg pain! I have 750km/470miles on mine!!! Where'd the time go? Feels like I JUST bought them a month ago!! Some shoe specialists say 800-1000km, some say 6 months, sore shins is always the sign for me. I was once told by a podiatrist that if you are running more than 3 days a week you should have two pairs of shoes and swap them out every day to give the shoe's support system a chance to recover. It helps to prevent injury and the life of the shoe. I guess it stands to reason that if you are running in the same old pair of shoes everyday the EVA is going to compress and lose its absorbtion factor and benefits. You might want to look at sciatica as a possible cause for cronic leg pain too. If my back muscles are too tight (ie I don't stretch thoroughly and often enough) it places strain on my sciatic nerve which then causes pain from my hips through to my glutes, hammies and then calves. I generally only get it on the right side, but since I've been diligently doing PNF stretching 3 times a week along with long passive stretching I haven't had any problems. As it is running and cycling are two of the worst exercises for shortening up your muscles, so having a really good 30 minute stretch after each workout is really a must for recovery and to keep the muscles from tightening up. |
