Mitchell eventually gave in.

　　Nicklin explains that big toe is surprisingly fit for a thumb switch: Nerves sync up (同步) nicely, and it looks more like a thumb, though a giant one, than any other alternative they may have come up with. He added that big toes aren't as necessary for balance and walking as people believe. As far as foot goes, occasional "fine balance" activities like surfing might be difficult, but most people without a big toe function fine in everyday tasks like walking and even competitive sports.

　　The eight­hour surgery went well, and Mitchell is expected to have a year or so of recovery in front of him before he heads back into the fields.
