Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to break in new pointe shoes [title] Identify the natural break in your arch. [step] Before you can soften the shank, the reinforced sole of the pointe shoe, you'll need to figure out where your natural arch breaks. The break is where the heel becomes the arch.

Ending1: If your arch has a weak point, you might want to hit it with the heel of your hand instead. [substeps] Your natural arch breaks down into an elongated cone shape, which resembles a stamp with stirrups on the bottom and open flaps on the front and sides. Ending2: The rest of the shoe restores the arch, yet it is covered by your natural arches. [substeps] Measure the foot to find the exact distance between the shoe's heel and the area where the arch meets the sole. Ending3: Figure out this by knowing where your arch would have rested if you were to jump in. Also, you can find the break more easily by looking at the back of your shoes. Ending4: Bend your foot to see where your arch naturally breaks. You can mark the point on both your foot and the shoe with a marker.
