The Serenade pointe shoe shank/insole gives support under the metatarsal which assists in holding the foot back in the shoe. The oblong-shaped platform with less height in the box helps give lateral support when 'en pointe'. This platform shape can help support a dancer inclined to sickle or fall off pointe sideways.
Narrow heel shape - Hugs the heel and reduces creasing
