I own a pair of the classic low cut style doc's, and am unfortunately a half size. Per Doc Marten's website, I purchased insoles to compensate for their lack of size selection. The problem is, they squeak constantly in my shoes. The sides of my shoes are leather, and the yellow plastic on the bottom of these rubs against them producing an obnoxious squeaking sound. Perhaps it is just my style shoe, but I am wearing a pretty standard Doc Marten style. They are made nice, and they were comfortable, but I just can't wear them due to the noise they produce. They were so loud, people on the street were commenting on how loud my shoes were! I put the factory insoles back in, and it fixed the problem, at the cost of slightly to large shoes. I suggest avoiding these, as they clearly are not designed for all styles of Doc's. Pharmacy brand insoles will offer similar quality comfort without the squeak, and the high price!
