The x max 130 is salomon top level 98 mm lasted all mountain boot. Although similar in fit out of the box as the ghost the x max has a full 360 custom shell. This means it is incredibly easy to get a great fit very fast. You need to ensure you have the footbeds correct before you do any stretching. Unlike regular pu boots you can't just heat the shell to unstrech so make sure you don't go too big.
Flex wise they are pretty soft for a 130 however acpect this shell to stiffen more when cold then regular pu boots. The liner is the lab liner so pretty thin and cold so these are high level boots don't expect super plush comfy liners. Look at the x max 120 if you want this.
The flex is adjustable from 120/130 and they have solid soles which are good for grinding.
Overall if you need a narrow boot and want a high level boot these are grey. We sell many more of the 120 though so look there too.
