Now you can kit yourself out completely with Fox MTB kit, with the all-new exciting addition of the Fox Union Shoe line. Years in the making and made with exceptional attention to detail, the Union range brings exceptional technology, unrivalled comfort, and supreme style, resulting in a riding experience that's second to none

The Fox Union Boa MTB Shoe is built upon a rugged Ultratack outsole made with brotobutyl, which balances next-level grip and durability. The glass-filled nylon shank and EVA outsole provide a stiff, responsive pedalling platform, as well as focussing on comfort, which is paired with the BOA Li2 Closure System and High-density padded tongue, which provides next-gen closure and comfort, as well as micro-adjustability on the fly. Added to this you have custom-tunable Insoles with arch support included, as well as the ability to purchase half-sizes. The welded construction and moulded toe-cap provide protection from the elements as well as rock strikes. A nice touch from Fox is that riders using 2-bolt cleats will benefit from the “Power and Control” guide printed on the sole to help you locate the perfect cleat position so you can max out your power transfer, or achieve precision and control.

Additional Features

  • Ultratack outsole balances grip and durability
  • Moulded, reinforced toe cap for protection against rock strikes
  • One-piece, welded upper provides a clean look and protection from the elements
  • Moulded heel counter for fit consistency and added durability

Great for my hot rod!
Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
Perfect oil for my hot rod! Add a bottle of zinc and you get great low temp flow as well as good heat protection. As a 0W it flows quickly for good start up protection and the 40W means I get good protection as temps rise. My car has a flat tappet hydraulic cam so I add a bottle of zinc. Has worked great!

European oil… Japanese engine… zero regrets 🇪🇺➡️🇯🇵

Yes, I know what the label says. “European Car Formula.” Yes, I put it in a 2002 Subaru WRX bugeye with an EJ257 block and EJ205 heads. And yes—this oil absolutely slaps. This engine is not stock, not delicate, and definitely not living an easy life. It sees spirited driving, boost, and the occasional questionable decision. After switching to Mobil 1 0W-40, cold starts are smoother, oil pressure is rock solid, and the motor just feels happier. No weird noises, no drama, no oil consumption surprises. The viscosity is perfect for a performance Subaru build, especially if you’re running tighter tolerances or want strong protection under heat and load. It’s thick enough when hot, flows great when cold, and inspires confidence every time I turn the key. Is it technically “European”? Sure. Does my Subaru care? Not even a little. If you’re running a built engine, turbo setup, or just want a proven, high-quality oil that punches above its weight, this stuff earns its reputation. My bugeye may not be European, but it’s living its best life on this oil. Would absolutely buy again—passport not required.
