My kid is both footed by birth, not design. We didn't know that this was rare or desired until we started to see a pattern from
coaches or parents. Usually went like this:
1. Oh, your kid is a lefty. cool. 2. Wait, your kid is a righty??? Both??? 3. After seeing my kid, coaches always ask my kid: which is your strong
foot? My kid answers both. I can use either one. Coach: Which position do you play? Kid: Left, right, center. I can play all positions.
Where I am going with this is that my kid can play either side left or right wing or center. Can take the corners,pk, fk, on either foot.
Can be moved around and subbed in/out. Flexibility and more PT. Injured players? No problem. Move over from left to right to center.
This is mostly by birth. If both footed could be taught or learned, then why not?
