FnM created an easy way to ID and purchase the foam I bought. The sock was a delight that no-one else offered. Having said that for me to sew a sock regardless of how easy it may be for others wasn't going to happen. I did have to cut the foam as it needed to fit in an intricate area. What a surprise I received when I took the sock off to start my trim. The foam was wrapped with this huge sticky "Ace bandage" so the foam wasn't exposed to chunk like the others I had gotten elsewhere.
I'm very happy with the intire experience and will be back for my foam needs!
