Shimano GE900 vs. GE900 HS: Two Shoes, One Path

If you prefer riding your mountain bike where the terrain gets steep, fast and rough, you will also have particular demands of your footwear. After all, the gravity segment is not solely about pedalling as efficiently as possible. A stable connection to the bike, sufficient cushioning and, above all, reliable protection for your feet and toes are at least equally important. Because as soon as a rock gets uncomfortably close or that root at the side of the trail catches your toes after all, a few saved grams quickly become rather less significant. Within the Bikeboard editorial team, too, we like to reach for models of this kind for review rides and shoots on unfamiliar trails. With the GE900 and GE900 HS, Shimano has two flagships for this style of mountain biking in its range. Both are designed for hard gravity use and, at least in terms of their fundamental focus, feel at home wherever things get properly serious. Whether in the bike park, on demanding enduro trails or full-blown downhill tracks, protection, control and the most secure possible connection to the pedal are clearly the priorities.

That said, the Japanese brand is pursuing two different philosophies. The classic GE900 aims to combine stiffness and mobility, while the GE900 HS, short for „Hot Seat“, uses a significantly firmer construction intended primarily to appeal to ambitious gravity racers. We have brought both models in for a long-term review through to spring. Luke Biketalker and avowed Shimano devotee NoSane will report back at the start of next season with an update on fit, intended use, durability and more.

It is obvious from the first contact that neither the GE900 nor the GE900 HS was developed in pursuit of every last gram saved. Both shoes are exceptionally robust, with substantial sole constructions, durable uppers and generously reinforced areas around the toes and heel.

Toe protection deserves particular attention in gravity riding. If you have ever clipped a rock or root at speed, you will know that a solid toe cap is far more than a nice design detail. Raised sections of the sole also provide additional protection at the sides against unwanted contact with the ground. Around the ankle, both models use an elastic neoprene cuff that hugs the joint closely and is intended to reduce the ingress of dirt, dust and small stones. It is a thoroughly sensible solution, particularly on dry bike-park tracks or longer descents through loose scree. A BOA Fit System combined with an additional hook-and-loop strap across the forefoot keeps each shoe securely on your foot. The GE900 uses a protected L6 dial, while Shimano equips the HS with the lower-profile Li2F version and revised lace routing. The protected position of the dials is intended to prevent contact with rocks or other obstacles from causing accidental opening or damage.

The basic concept is therefore similar for both shoes: straightforward entry and removal, finely adjustable fit and the most secure possible hold when things get serious on the trail.

There are numerous similarities when it comes to the outsole. Both the GE900 and the GE900 HS feature Shimano's ULTREAD-GE outsole, whose rubber compound and tread pattern were developed specifically for gravity and enduro use. On the one hand, it is intended to provide reliable grip while walking or pushing; on the other, it should deliver as much control as possible on the pedal. To achieve this, both shoes feature a pronounced pedal channel designed to provide a stable platform on suitably constructed SPD pedals even when you are unclipped. Another interesting detail is the extended adjustment range for the SPD cleats. This allows the cleats to be moved comparatively far towards the midfoot. That position is often preferred in gravity riding because it supports the foot more centrally over the pedal and can reduce the load on the forefoot. If your priority on descents is less about achieving the smoothest possible pedal stroke and more about a stable stance, this may catch your attention.

So far, so similar. The crucial difference between the two flagship models, however, lies one level higher: in the construction of the midsole.

For the classic GE900, Shimano uses what it calls TORBAL 2.0 technology. This is a carbon-reinforced midsole that provides a stable platform in the central area while still allowing targeted torsional movement. A certain degree of mobility is retained, particularly at the sides and towards the rear of the sole. According to Shimano, this is intended to improve control over the bike by preventing the shoe from behaving as a completely rigid structure during rapid changes of direction and through corners. The construction is complemented by multi-layer EVA cushioning, which is intended to absorb impacts and vibrations, thereby providing additional comfort and stability. On paper, at least, the result is an interesting combination: stiff enough for efficient pedalling and a secure stance, yet flexible enough not to restrict the foot's natural mobility completely.

That character is also apparent when you first try the shoe on. Although the GE900 feels exceptionally solid and by no means soft, it rolls through the stride much more easily than the HS in a direct comparison. As a result, it feels more natural and less cumbersome when walking. That may initially sound like a minor detail, but it can certainly become relevant in everyday enduro riding. After all, not every trail finishes directly at a lift, and the route to the next descent sometimes includes a few metres that are better covered on foot. It also matters during our shoots. With NoSane stationed in the undergrowth as photographer and the rest of us repeatedly walking back to the photo point as riders, good walking characteristics pay off everywhere.

Overall, the GE900 presents itself as a versatile gravity shoe that aims to bridge the gap between aggressive descending and a certain degree of everyday practicality. Our hypothesis: it may not necessarily be everyone's first choice for hours-long rides with countless metres of climbing, but it could be an interesting candidate if you like to push hard on descents without immediately considering a change of shoes at the first hike-a-bike section.

The GE900 HS, by contrast, takes a far more uncompromising direction. The name „Hot Seat“ already suggests that Shimano is primarily targeting riders for whom descending is not only about fun, but occasionally about fractions of a second too. At its heart is the FORCE-CONTROL midsole. Unlike the deliberately mobile TORBAL 2.0 construction of the GE900, Shimano gives the HS particularly high stiffness. It is paired with a substantially firmer EVA foam, intended to provide a stable and precise connection to the pedal under heavy loads. The rationale is easy to understand: when you are charging at speed through rough rock gardens, deep compressions or fast berms, the shoe should permit as little unwanted movement as possible while reliably supporting the foot.

Whether the additional stiffness genuinely results in greater control, and how noticeable the firmer cushioning becomes on long descents, remain open questions for now. What can already be established without cleats fitted, however, is this: although Shimano assigns both models a stiffness index of „7“, the HS feels noticeably stiffer than the standard GE900 in a direct comparison. This is particularly evident when you try to roll naturally through the shoe while walking. It is a good example of why a single figure never tells the whole story. After all, it makes a difference whether a sole is primarily stable while pedalling, permits lateral torsional movement or behaves as naturally as possible when walking.

The GE900 focuses on the combination of stiffness, cushioning and controlled mobility. The HS, by contrast, prioritises the firmest possible platform and a direct feel beneath the foot.
