According to a former elite runner and now a coach of famous US elite runners, a runner should change his/her shoes every 500 miles or 800 kilometers of distance covered. If a runner exceeds this distance, he/she is inviting injury that could stop or completely destroy one’s training schedule to a particular running event.
Sometimes, it is very hard for us to decide to buy a new running shoes even if the physical appearance of the “old” shoe is still almost new. But one should think that it is better to prevent oneself from being injured instead of paying more in order to cure one’s injury. “An ounce of prevention is better than a pound of cure”. Spending 4-8 Thousand Pesos of a brand-new running shoes is better and cheaper than being cured by medicines, physical therapists, or surgery.
I am sure your old shoes will still be useful if you give them to your household helpers and their families or better yet donate them to my project—Donate-A-Shoe. Those runners who can not afford to buy a brand new running shoes will be happy to receive them.
My ASICS Gel-Cumulus 8 is about to be separated from me soon which I bought last December 2006 at Phidippides Running Store in Encino, California. I used this shoes for 4 months in preparation for the 2008 Pasig River Marathon last February 2008 and was able to finish the said marathon with this shoes to include half-marathon, 15K and 10K races. This shoes had done a splendid job and still looks very new. Whoever will get this shoes (with my signature on the insoles) will be happy to own one of the “Bald Runner’s Running Shoes”.
