The Five Ten Hellcat has for many years been the default go-to choice of shoe for competitors on the World Cup Downhill circuit which goes some way to explain why the Hellcat has more UCI Downhill victory medals to its name than Michael Phelps has Olympic gold medals.

This new Hellcat isn't a whole lot different to the 2019/20 version, it still features the leather and synthetic upper for durability and weather resistance and it maintains the 3/4 dual-density vibration-damping TPU shank, this allows the sole of the shoe to flex whilst walking around but maintains rigidity whilst pedalling.

Not everything is the same, just like the Hellcat Pro, the new Hellcat features Adidas's unique Boost™ Midsole which offers endless energy in the mountains and high adaptability on rocky surfaces, another change is the switch to STEALTH® Marathon™ which doesn't quite offer the same amount of grip that C4™ did but is significantly more durable and non-marking.

Further improvements are around the clipless interface, on previous versions of the Hellcat the rubber sole met the edges of the recess in which the cleats were mounted, this often meant that over time the constant engaging and disengaging from the clips damaged the rubber around this recess. For the new Hellcat, however, the rubber sole is further back from the recess intentionally exposing part of the much more durable TPU shank which itself has been shaped to further aid cleat engagement.

Recommended Use

The Hellcat was born to descend hills and descend them as quick as possible with its new weather-friendly leather upper and moderately stiff midsole for a balance of pedal feel and power transfer.

Fitting Advice

The sizing for Five Ten shoes has shifted over the past few years, historically the shoes were famous for being quite roomy so riders would often size down. However, the later models such as anything with Pro in the name feature a more athletic, a narrower, closer fit for performance.

We'd recommend you follow the sizing advice below, testing a range of models in the office (a member of staff, typically wears a UK 10/Euro 44 and a 280mm foot length) always opted for UK 9.5 with the exception for the Freerider Pro, Impact Pro and Trailcross ranges for which he sized up to a UK 10.

Measuring Tips

Five Ten Shoe Sizing Five Ten Shoe Sizing Five Ten Shoe Sizing
  1. Place a piece of paper on a hard floor with one end of the wall, stand on the piece of paper (wearing socks) with the heel slightly touching the wall.
  2. Mark the end of your longest toe with a pencil for both feet, it's easier if you let someone help you with this.
  3. Measure your marking from the wall (heel) to the longest toe for both feet, take the larger of the foot lengths and compare it with the sizing chart above to work out your ideal Five Ten shoe size.
