Women: 1.5 sizes down from street shoe size
Men: 3.5 sizes down from street shoe size
Elektra Tech pointe shoes should fit snug around the foot so that you can feel the box with the end of your toes but they shouldn't be crunched.
The shoe is the correct length when the shank housing lines up with the base of the heel while on the box.
These shoes are so comfy that it can be deceiving to know when you have the correct size.
For this reason, your first pair needs to be fit by an Elektra Tech specialist.
