Extreme nature biking

Ah I thought that might be the explanation for the pedals. Didn't think in a million years they'd be doing this brakeless fixed.. but legends are legends.

Do they have separate hiking shoes and riding shoes as well?

I doubt it...most hiking boots have slightly stiffer soles anyway...most snow bikers and adventure bikers use hiking boots for more comfort and protection...the last thing you want to do is slip on ice still clipped in and sprain your ankle out in the frozen wastes of Alaska. :)
