Hi Mizunoman,
Yes I am currently using the new Mizuno Nexlite BOA005 spiked golf shoes,
And so fare I've found them to be an excellent golf shoe very light and comfortable to ware and offering very good grip IMHO, my shoe size is a UK 10 and I also have a broad foot and I don't find them to be tight in this area of my feet,
This is the first time I've had a pair of golf shoes that don't have conventional laces and they felt strange to ware at first but I soon got used to them the Boa
system works really well only thing I found was after walking and playing a few holes I would have to give them a click or two to tighten them up a bit as my feet settled more in to them,
Hope this helps
Cheers
John.
