There were other female related items besides shoes.
That group hasn’t found anything that can be actually linked to Earhart. The shoes were the wrong size, the bits of plane had no serial numbers that matched, and could have been salvaged from any one of the 8 planes of the same type that crashed or were decomissioned in the area. The “female” bones turned out to be male bones according to other reports, and some even question whether they were caucasian bones at all. They ended up in the trash, so nobody can say for sure now.
