Just took delivery of my Vaypor's over the weekend.
They weighed in at 255 and 256g for size 44 in normal width, microfibre uppers.
They sure felt weird out of the box being tight in many wrong places.
Bit the bullet and tried heat molding the right foot first. And hey .... the results were fabulous! Fits really good after that.
Now, there were fears of over heating the shoes in the oven as the tiny toaster oven I had in the kitchen didn't even have temperature settings!
So basically used the hairdryer in mid-setting, and heated the shoe up by directing the hot air into the hollow of the shoe. Took something like 10 minutes, leaving the shoe and hairdryer lying on the floor. And it was 'warm enough' as you can detect pliability in the side skirting of the shoe.
Wore a pair of thicker than normal socks to simulate foot expansion while riding and basically fitted up and started to get the shoe to yield in those hotspots.
All said and done, it took me about 3 cycles ( about 1 full hour) of repeated prodding and heating to get that comfy fit I wanted from 1 shoe. But its really well worth the time once its done. The second shoe took considerably less time, maybe 35~40 minutes total to get sorted out.
Only grouse with the shoes really were that various details on the shoe don't look the best of build quality for shoes of such price bracket compared to say Shimano or Sidi. But only time will tell if they are durable.
Bottom line: The time spent on heat molding the fit is well worth it. Just don't rush it.
