Choosing among ski & snowboard bindings and boots gets complicated when two very different boot types are competing for the same purchase. The useful shortcut is to match the boot category first, then weigh the Head's size-specific, pre-owned setup against the System's snowboard-focused fit and flex features.
Quick verdict
Choose Head BYS HP Ski Boots for alpine skiing, provided its Mondo 34 and US 16 sizing fits your needs and pre-owned condition is acceptable. Choose System APX Men's Snowboard Boots for snowboarding, especially if heat-moldable liners, an articulating cuff, flex panels, and waterproofing are priorities.

Product notes
Head BYS HP Ski Boots - Size 16 / Mondo 34 Used

Head BYS HP Ski Boots is the straightforward pick when the purchase is specifically for alpine skiing and the sizing matches. It is identified as a ski boot in Mondo 34 and US 16, with a 365 mm boot sole length, giving the fit decision several concrete size targets. The clearest limitation is condition: the boot is marked used and pre-owned, and it is described as cleaned and refurbished. That makes prior ownership part of the decision. The multicolor finish and unisex department label are useful descriptors, but neither changes the central fit question. Choose Head when ski-specific wording and the exact size format matter more than getting a snowboard boot with named design features.
System APX Men's Snowboard Boots

System APX Men's Snowboard Boots is the targeted match for a snowboarder who wants clearly specified fit and flex features. The boot includes Thermofit heat-moldable liners, an articulating cuff, built-in flex panels, and waterproofing, creating a feature-focused choice for snowboard use. The limitation is equally clear: it is snowboard footwear, so it does not match a shopper seeking an alpine ski boot. The APX is presented in a traditional-lace model and an upgraded Pro Twist model, making lacing approach part of the product line's distinction. Pick System when snowboarding is the intended use and those liner, cuff, flex, and waterproofing features matter more than the ski-boot format of Head BYS HP Ski Boots.
Final choice by use case
Choose Head BYS HP Ski Boots for alpine skiing
This is the cleanest category match when the goal is a ski boot. The deciding details are the Mondo 34 / US 16 sizing and acceptance of pre-owned condition; those points separate a fit-and-condition decision from a snowboard-boot purchase.
Choose System APX Men's Snowboard Boots for snowboarding
This is the direct pick for a snowboard purchase. Choose it when the Thermofit liner and waterproofing are useful priorities, alongside the articulating cuff and flex panels. If the use case is skiing, Head's explicit ski-boot identity is the better match.
