My daughter loves her twinkle toes shoes and wished they had made some for her American Girl dolls. I started looking around for some plain tennis shoes that would fit and used gems to make our own.
Plain toed tennis shoes that fit your doll -$4 from amazon
Tiny gems 1,500 for $2 from amazon
Hot glue gun and sticks
Glue the gems one or two at a time on the toes until all is covered.
They turned out very cute and I plan on making another pair for her other doll too.
