This is probably my 5th pair of keen ?steel toed? work shoes. I did have to poke a hole in the straps in order for them to stay on my feet, I have skinny ankles, but I still gave 5 stars because that is not a huge deal to me. I wear size 12 or 13. Yo the speakers are Amazing! The sole is solid - not like so many slippers with cheesy rubber soles that are so flimsy. Great for basic hunting purposes It is easy to put on my RAV4 and I can easily carry mine & my friend?s bikes everywhere. Even 12 felt like too much for me. This popped up around the 3 month mark. These shoes are true to american sizes and so fitted perfectly.
