Over 20 years. Saucony owners! Wear less than 2 hours and the entire front of the sole will come off. I contacted the seller and instead of accepting the exchange I was asked to go to the Sauconys website...not even provided a website had to look it up yourself! and write a complaint. (the seller only sells them for $25 more than I paid) Luckily Saucony is a great company who fixed the problem and replaced the faulty shoes and processed the claim very quickly! Plus, they're a lot cheaper on the Sauconys website, and their return policy really means something! Sokoni is great! Good product! I will no longer do business with this seller.
