I have been wearing these comfortable and durable shoes every day for the past two years often clocking from 6000 to 13,000 plus steps per day. I am through the outer rubber on the bottom heels now.
Today, after reading comments about using baby powder to eliminate the noise on this site, I decided to give it a try. I have carefully pulled the inner liner out (which has been glued down with multiple parallel strips of glue) and applied a few tablespoons of baby powder to both the inner shoe and the bottom of the inner sold on each shoe. Problem solved.
This is a super shoe: durable, light, comfortable and all black so they look good with casual clothes. My recent pairs are quiet.
