Got some DMs a couple of weeks ago. I have been wearing Solovairs but decided to give DMs a try and there was some rubbing on my left heel for the first few days but now they are excellent so far. The insoles seem to fit me perfectly as I find that I need support in the middle of my foot and these provide it.
The two on the left are DMs. The three on the right are Solovair. Modern DMs are crap compared with vintage ones so I'll be sticking to Solovair from now on.
