Not sure about the price, but I don't think they'll be more than, say, a pair of Road Champs.
Update: 59,800.00 JPY / $780.762 - not a bad price at all!!
That is definitely some food for thought - I wonder if they will be as nice as your Beck's or the Road Champs. The Becks in particular look like they are made from super thick leather - unfortunately, it didn't look like they made them in a size 13.... I was looking those up yesterday and getting quite a hankering for a pair.
