I have been working in the yard for a total of 13 weeks, so these are still relatively new. That said, the shoes are very comfortable. I rarely think about my feet when working, which means they are performing well. The grip is excellent as is the support. Summer will present heat challenges, so I can't tell yet how the Kujos will do then. I have two concerns with the shoes. First, the lime green accent near the top shoelace hole was coming loose when the shoes arrived. Made me wonder about the build quality. The second just occurred recently. The loop at the back of the shoe is starting to come loose. A second time I am wondering again... I want to love these shoes, I really do. We'll see.
