The boots are comfortable and lightweight. Less than a year after I bought them I started to notice what I thought was dirt or maybe hydraulic fluid. I slowly began to realize it was the adhesive for the book seeping out of the fabric of the boot. Most recently I have noticed (once it started to rain) that the sole of my boot was falling apart and when my boots got damp, they would squeak when I walked as the air was pushed out as I walked. These boots were and still are lightweight, breathable and very comfortable. Apparently just poorly made. Hopefully this pair was a fluke. Good luck.
