The BalancePlus 400 is the newest release from the number one curling shoe company. It's a hybrid between the 200 and 500 series shoes. It has an upper that is very similar to the 200, and a split sole similar to the 500. The main difference between the 400 and 500 soles is that the split slider / gripper is glued onto the sole, rather than attaching with velcro. The benefit to the split slider is increased flexibility and ultimately a little more comfort, whether you go up on your toe while delivering, or just going up and down the sheet sweeping. Available in ladies 5-10, 11 and mens 7-12, 13, 14, 15. Toe coating optional.
