My son is 8 and 56 pounds. His friends at the academy have snowboards they ride on the hills there. Does this board provide good maneuverability?

what is the weight limit on this

typially what shoe size does it hold my son is 12 with a size 11 shoe?

3 snowboards given to my 3 sons for Christmas. First snow 2 weeks ago and straps broke on each board. How do I go about requesting replacement straps?
