Yes, I've found the same. The weight I can deal with, but mine get so drenched with sweat that I can squeeze it from the tips of the laces. I generally have two pairs in rotation, but with the SCB two pairs is what I need each time I play.SCB with aftermarket inner soles is ok on hardcourt BUT they should be called Sweat Court Bounce. Totally non breathable. I guess an aspect of the decline of shoes is some other factors like this. What they think we play in aircon? Not in Australia. Not usually. (Not ever!)
SCB for cushion sake is quite good but so rubbery that the upper has to be pretty sturdy itself. Each shoes is also almost 500grams. So a total of one kilo of rubber gets v hot in baking sun and UV. Even then the upper doesn't seem to control the sole. As heavy as it is. Don't think they cld introduce holes or airways without compromise the unit.
