The fourth generation running shoes of Red Rabbit have good protection, built-in TPU, moderate hardness and ergonomic design. The filling sponge is slightly thicker, the wrapping property is improved a lot, and it has a more heel feeling. The disadvantage is that it may be a bit boring.

The uppers for the fourth generation red rabbits are jacquard and single-layer mesh. The texture is light and thin, and it has the feeling of micro-elasticity. The mesh surface has high toughness, and it should be no problem within 300km under normal running intensity.
