I've had three pairs of the Conall Lo Sneaker over the past 4-5 years. My first pair was purchased at Nordstrom Rack and held up excellent for 2-3 years. A matter of fact, I still have them and wear them, but took them out of my day-to-day rotation solely because of how worn and dirty they look.In the past ~2 years, I've purchased two replacement pairs and in both cases the cardboard feeling material that provides structure to the heel has cracked or shattered after 1-2 wears (not weeks or months of wear). The one pair is barely wearable because of the pieces migrating around the inside of the fabric and creating lumps and areas of discomfort. I never had this issue with my original pair and wonder if there has been a decrease in build quality. My second and third pair were purchased about a year a part so I doubt it was simply a "bad batch".
