Prevent scrunched toes in high heels by asking a shoe cobbler to trim the heel down for you. Sometimes, the angle between the heel and the ball-of-foot is too great, causing your feet to slide forward and squish your toes against the front of the shoe. Reducing the heel height might fix this. Do not attempt to do this on your own; seek out a shoe cobbler to do it for you. Most high heels can be trimmed down up to 1 inch (2.54 centimeters) by a shoe cobbler.
