I was a V3 fan. The V4 model that this shoe is does not have the same quality and does not fit the size of the previous versions. While I'm a fan of the mesh front to reduce heat, the shoe's toe box feels fun. My finger rubs the shoe where it wasn't before. The lining at the back of the ankle is stiffer and also rubs the ankle. The price has stayed the same, but in general the shoes seem "cheaper".
