I've worn mine for 8 months, but:

1) you have to try them on for sizing (mine are 8.5D and a bit loose with regular work socks; I only wear EE to 4E in shoes and boots)

2) not much comfort for wearing all day, absolutely need quality sole inserts ( now + $25. for true cost)

3) I use mine for heavy outdoor yard work, like digging in mud. Tried climbing trees, not a good idea. The greatest benefit is the quick on/off, which is one of the main reason why I bought these.

Mine are holding up well, but I clean them every week and have treated them at least 2x with mink oil.

I recommend going to a local Red Wing store to check them out.
