This is my second pair of Keen Austin in two years. Both pairs began to squeak at about 9 months old. The first pair began to squeak at just over a year old. Great shoes but could not wear them any longer as they were to noisy. Bought another pair. After 9 months, this pair began to squeak just like the prior pair. Is not the insole. Squeak is there when insole is removed. Have purchased Keen shoes since 2006 and the latest 5 pairs have all been poor quality. They either squeak or the soles fall off due to adhesive failure.
