Definitely not comfortable. Highly recomend. Because it is a USB mic, you dont need an audio mixer or interface for this to work. But my insert is quite thin and Id still go with a 12. but the Velcro came unstuck from the shoe. Unless I intentionally try to keep my feet centered while walking (which would be very difficult), these shoes would quickly become very uncomfortable to wear due to my toes and ball of my foot feeling the sharpness of that edge. I will not however buy another boot from Georgia Boot and I can’t recommend them in good conscience. I was a little worried at first, but upon arrival I was very happy with the quality of the product. Pop filter and XLR included for the same price as the mic by itself is another bonus. 5 with wide feet and the size medium fit great.
