April I have two pairs of Doc Marten boots one with a regular sole (floral docs) and the other with the thicker platform sole (Hello Kitty docs). The thicker sole is rigid and less comfortable than the regular Doc Marten sole because it is far less flexible and it does not seem to change with wearing them in. I would recommend not getting the thicker sole, but going with the regular because I think you will find them problematic.
The good news is that the regular soled Doc boots are a complete winner. I have travelled overseas with these boots and done 20,000 steps a day in them with no complaints.
I had not worn Doc Marten boots in years but rolled my ankle and needed support and they were brilliant. So my recommendation is YES to Doc Marten boots but with the regular sole for maximum comfort.
