Shoes uppers for crafting or resole (Penrith CA11)

These have all succumbed to the dreaded hydrolysis of the sole, even though hardly worn and leather uppers hardly showing wear. Soles are disintegrating and sticky, Doubtful they could be reliably repaired economically. Would anyone like to teach them selves resoling or use the leather uppers for craft projects? I hate to waste good leather! Size 51/2 or 6 if re- soling is in your skills list ;) end shoes Rockport, middle Clarks! Beware hydrolysis!
