BIFL post, Thorogood WP 814-3800. 18 months of aircraft maintenance in the US PNW. Recently resoled, no other care or maintenance ever done and no failures or leaks.
Left (I believe) is a discontinued pascal Dr. Martens, right is Solovair derby. I am trying to find something similar to the left one: more streamlined, wraps naturally around the foot whereas the right one expands outwards and looks like a clumpy boat.
