There's a fundamental point with brands like this that people don't quite grasp.
If Sports Direct are making a running T, they just need to cut 5 pieces of fabric and arrange them into a shape where people can put their head through a hole in the bottom and emerge through a hole in the top, and two more to fit an arm on each side. If the shape and size is approximately right and the material's correct, it's a functional product that requires no testing.
When you're talking about putting a shoe on your foot, a whole new world of biomechanical variables come into play. It's not just a matter of apeing a shoe shape, cutting the bits out, glueing them together and assuming everything will be rosy.
My suspicion is that they've created a running shoe "look", but have done zero research and testing in terms of stability, feel, ride, cushioning, response, and everything that's important to someone that's going to go out and run in them.
