Single Tube Damper Design
- Mono tube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and center of gravity gives a more stable ride.
Dust Boot
- Protect the shaft from the flying stones.
PNE Coating
- Using this special surface coating provides 5 times better durability over standard galvanising. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.
M Shaft (?46 normal type)
- With the new design of cylinder shaft since the HIPERMAX M-1, MAX IV increased the cylinder shaft size to have a firm damping even at a little stroke range by optimizing the oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.
Adopted Pillow Ball Upper Mount
- For more accurate and sharp steering.
New Design Needle
- Newly designed needle has been used to revise the very low speed and middle and high speed dampening which is key to a comfort ride.
Reduction of Unsprung Weight
- In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminium. (Not for all vehicles)
30 Step Damping Force Adjustment
- 30 levels of dampening adjustment allow fine tune adjustment for street, circuit winding roads, highway, or the weight of the vehicle.

Size up
Size: 2 Big Kid, Color: Black/Pink
My daughter loves them. However they run a size small so we had to size up. She is anywhere from a 13-1 and we had to get a 2 in these. Overall great show and quality. She also just learned how to tie her shoe (7yo) and they are easy for her to tie. Style is great for running and sports too. Overall great value for the money.

These shoes make a great first impression, but beware of the stingy toe box.
Size: 13.5 Wide Big Kid, Color: Black/Orange
These shoes make a good first impression. They look sharp and appear to be well-made for running shoes. They also get bonus points for having actual laces instead of the common velco/fake laces combo. However, my son struggled to get them on at first due to limited room in the toe box. He has wide feet as well as high arches and the shoes were very snug across the top of his foot initially. Once he got them on, we determined that they were both wide enough (which is a rarity in itself) and the right size – just tight across the top. I actually had to remove the insoles to get them on his feet at first. After a few minutes I tried again with the insoles and he wore them around the house for a few hours, at which point the upper material had relaxed and/or the footbed had started to take on the shape of his foot, in effect creating more wiggle room. By then he didn't want to take them off, so they must have gotten more comfortable after that brief break-in period. If they were still too tight I'm sure he would have complained. I'll update the review if the shoes wear out prematurely or there is anything else noteworthy to report.

Sole separation
Size: 3 Big Kid, Color: Black/Orange, Size: 3 Big Kid, Color: Black/Orange
I really dont like to write reviews, let alone a negative one. Have had the shoe 1 month and the out sole on both shoes are peeling up. Normally we have had great success with saucony shoes for my boys. But this one we haven't had good luck. I have been super gluing the soles back down everything they peal up. Hopefully this is just a 1 off incident. Both side of one shoe and a large chunk of the heal on the other. You can see the glue marks and separation in pictures.
