OK, those feet are pretty damn wide... 10.5cm for size 7!!?? Yeah, with my SC5EX I needed to up half size too to 9.5. But 9000/9100 was perfectly fine at my normal size 9. Even the A930 that's coming to me, I ordered in 9.5 just in case...
First of all, congratulations! I am currently checking out my last and final possibility to get the blue 920s at least for a halfway acceptable price (through Racquetforce and in the luggage of a colleague from my companies HK office...). If that doesn't work out or if I finally lose the fun in this quite annoying shoe-hunt, I will definitely go for the S80. According to your review, they would also fit the bill perfectly. But they are not BLUE!!!!
Bloody hell - I don't know where Ben's found them... I was so close to pulling the trigger on those, but I'm waiting till next season.
Oh boy, you're asking a tough question here. I like both shoes! Both are very good in respect of providing support and there is plenty of cushioning. I would say 80 is a lighter shoe and it has a slightly different shape which means it can be more forgiving on a wider foot. I am currently using 920 which I really love.
