I emailed them and this is what I got back.
"The entire sole of each shoe is intertwined with the body of the shoe, so replacing a sole would affect the shoe's structural integrity. Also because the soles are handcrafted and hand punched, no replacements are possible. "
They won`t fix them for you, they don`t do repairs. Tod`s are extremely expensive, disposable shoes. Once the sole has worn down there is no replacement that will fit them and no cobbler i`ve spoken to can fix them. People should know this before you drop 700 on a pair of their shoes. They don`t give a shit about their customers. This is the last time I buy from them, ferragamo is so much better.
