How? Can I fit an iPhone 5c into a iPhone 5 RUBBER not plastic, case?

Like the iPhone 5c Width is 2.33 inches (59.2 mm) and Depth: 0.35 inch (8.97 mm). While the iPhone 5 is Width 2.31 inches (58.6 mm) and Depth: 0.30 inch (7.6 mm). So I'm getting the iPhone 5 Vans waffle case

So can I like squish the 5c into the Vans RUBBER case since its rubber it can stretch.

I would not purchase any case that is not designed specifically for your phone.

Some of the rubber cases are hard rubber and do not have a lot of stretch to them. So even though the case is rubber, it may not fit.

I have a rubber case for my phone. It is hard to put on and take off the phone and it is specifically designed for my phone.

IPhone five cases do not fit on the iPhone 5c. And honestly the 5C does not need a case.
