Stretched model on importing

[Autopilot]

Hello guys, I am facing this issue when I am uploading the model in Mixamo. One part of the shoe is getting streched abruptly. The issue can be seen on the shoes part. Need your help to fix the issue. 

Thanks in advance. Cheers.

the issue is because your dress is hiding the legs and I'd remove the outfit or try putting the legs apart more before rigging
