A few weeks ago, while listening to the Knit Picks Podcast, guest Sandra McAlister talked about knitting the bottom part of socks inside out, creating the purl stitch on the outside of the sock. This means that the knit part of the fabric on the bottom of the foot eliminates the "knobbiness" of the purl stitch closest to the skin.
Several people even commented on the show notes that this technique would be great for a person with diabetes and those ever present foot ulcers common to diabetics. Sandra knits socks in this manner because she is a long distance walker, and blisters are less likely to occur when walking long distances if the sock is smooth where it touches the bottom of the foot.
What a great idea, huh? So I made the second sock of THE PERFECT FIT Socks by Becca in this manner. Here is how the heel and bottom of the feet look with the purl side to the outside:
As soon as these socks are dry and off the sock blockers, I'll be anxious to see if there is a noticeable difference in foot comfort while walking.
