text: Been wearing NB size 9 4E hiking shoes for about 8 years. I am an active day hiker. Never had a problem till this model. Bought these in 2014 but didn't start using them till 2015. Soles separated from shoes after 6 months of hiking. Way too expensive to replace twice a year. Now need to find another brand in my size. Too bad, I liked the fit and comfort.
