I am a "bat" guy. Bought at least 20 bats in 12 years. Save them all.
When my DD is grown and out of softball, I will be sitting in my rocker, looking at a bunch of bats, telling stories about which "bat" hit what, and when, those darn bats gave me joy.
My DD's are going through cleats before they can even wear them out completely. One DD is size 10 Womens (13y.o.) and the other is size 12 Womens (12 y.o.).
Mine broke through her toes of her cleats this fall. I just ordered a new pair in size 8 mens from Amazon. I think that's basically the length of a womens 10, but wider. In my memories, there were very few girls with shoe sizes this big when I was that age, now they're everywhere.
Maybe your 12 year old can pass cleats upward (LOL) to her older sister?
