I bought a similar pair in 2016 and love them. But this time I paid double the price and was very disappointed with these NB shoes. The top of the sneakers only started to diverge after 10 hours of wear. Another complaint I have is that these shoes get very hot to me. After 30 minutes of walking, feet are very hot. I suspect the quality of the materials is different than what I had in 2016. I was abroad so I couldn't return them within 30 days or I would have. Very disappointed and wish there was a way to write NB!
