We purchased 2 pairs of youth mud puppy boots for out 6 and7 year old sons for bird hunting. The boots cracked within the first three weeks with limited wear. We patched the cracks with shoe goo waterproof repair silicone. They outgrew them that winter. We purchased another set (2 more pairs) last Dec.2009 and they wore them last spring for two months before those split also. Four pairs of boots, all cracked after minimal wear, no return calls from Itasca, $180. of boots wasted, can someone help????
