Replying to Are these Full Tilt shells trashed?

Hi, I tend to buy up old Raichle and Full Tilt boots when I see them in (thrift shops or on Ebay for minimum bid) and strip them for parts. Recently I managed to get some nice Seth Morrison boots with the red translucent shells. But they have had a hard life. They have grip walk soles and the previous owner seems to have gone moto GP riding in them looking at the wear! I put some new sole units from a K2 FL3X TW on them but there's a big gap. Plus the K2 units are a lot thicker.
So the question I'm asking: are they trashed or would you use them?
