Toes have weak little muscles from shoewear. Give them a tug to strengthen them. Toes also like to be stretched and rotated.
I just finished a pair of feet for a client. She had told me she was at a family gathering and told them about my thing about toes crossing over.
Over the years I have found that when toes cross over each other, memory frequently becomes an issue. So my advice is pull them, stretch them and rotate them to tune up the old noggin.
My client said before long everybody at the family gathering was inspecting their toes. I just hope they remember to work on their toes.
