Got the 8. Worked the hell out of those boots and feel I can expect the same from these. Sturdy too! It was very uncomfortable after a few minutes to the point that I had to remove the earphones. I got this for my girlfriend so she could listen to her podcasts, YouTube videos, or music in the shower. Myers beach this past month and took 2 bikes along with us. Solid shoe, but unlike some of the other gardening style rubber shoes I have, these have no air flow in the front of the shoe so your feet get pretty warm. For me, I am returning the Gloryfires because the sound in the left ear is quiet, my Walkers crapped out after a few months, and the Impacts are what several of the ROs at the range I go to wear — haven’t had them long enough to gauge their reliability. The rubber piece that goes around the ear is very comfortable and fits and adjusts behind the ear great and is very sturdy, as I have gotten others that were very flimsy. Happy to say my cat is eating dry kibble from this bowl even the tiny bits at the bottom.
