Yonex Workmanship Issue?

Recently (about 3 weeks ago) bought a pair of new shoes (Yonex Power Cushion SHB-SC6EX Ocean Blue) for my kid. One night just before a major tournament when she's practicing in the gym, she found the sole of her new shoes separated from the top. Given she trains about 4 times a week, and only wears her shoes for badminton, this is an alarming rate of breakage.

Prior to this pair, she'd a seemingly early breakage with her Yonex SHB-86EX 2012 Black/Orange, which got holes in multiple places.

Did anyone have a similar bad experience? And in the first incidence, would there be a case for warranty claim (on workmanship)?

The 86 is quite famous for having holes in them after heavy use. Even the 65FT which is its Japanese counter part is also susceptible to this as well.

may have been its design but I'm sure as all comfy shoes, they're less durable compared to tougher shoes.

Maybe it's time to switch to a different brand?
