Had high hope on these. Think that it's such an awesome idea. However when you put it in use, it's kind of flimsy. Unless you have pure soil you can dig, if there are any rocks, roots, wood chip... Good luck to your fingers.

I bought this knife December 2018 and has been great thus far. The only downside is that the clip used to attached the knife to a pocket or belt is held by 3 small screws. With time and the weight of the knife one of the screws stripped and no longer held the clip in place. I remedied this issue with a drop of gorilla glue. Now it doesnt move and holds the clip and the knife in place.

I've been wearing Clark's 9M for over 20 years and they always fit perfectly. Unfortunately the last 2 pairs of Clark's that I have ordered have been at least a half size too large. Either my foot has shrunk, or Clark's has changed their sizing. This is a cute style, unfortunately these shoes won't work for me.
