Purchased a pair of the bison boots under the graded quality section of the site. I am unsure where the graded quality is honestly. I am using these boots as everyday boots. I wear them to the office where I stand most of the day and they work great. I might swap the insole for a leather insole though. Out of the box the boots are pretty comfy but after wearing them for a full workday I do believe that I'll need some more time to properly break them in. Look forward to wearing them for years to come! My feet are a little wide so I do appreciate the EE size being available.
