Gear review | The BOA® Fit System

Ritual - "Ratsch, ratsch": A first impression

When you first put on the Salomon Shift Alpha 115 with BOA system, it becomes clear that there is more to it than just a technical gimmick. While classic buckles often tighten awkwardly and asymmetrically, here you can feel how the boot fits snugly around your foot with even pressure distribution. No readjustment is necessary, you simply turn it until it feels nice and tight. When standing, you can feel that your foot is tight but not squeezed. To take them off, simply pull the wheel slightly upwards. With this quick release, the tension is completely released with just one movement.

The BOA system also makes a well thought-out impression in terms of handling. Operation is intuitive. Even when wearing gloves, the twist lock is easy to grip and adjust. This is particularly practical if you have laced the boot so tightly that you need to loosen it again during the lift ride: A quick twist is all it takes and the boot fits perfectly again. This means you can easily keep up with the snow-hungry people on a powder day if they don't want to wait.

The BOA system does not replace all the fastening elements of a ski boot, however: the upper buckles of the Salomon Shift Alpha 115 are still classic. Thanks to the interplay of modern technology and proven mechanics, the BOA system does not look like a radical break, but rather like a sensible step forward. It is particularly suitable for anyone who values simple and precise adjustment. Personally, however, it's usually the upper part of the ski boot that causes me problems, be it due to shin pain or the constant feeling that the boot is either too loose or too tight. In this respect, a perfect fit in the lower area can only contribute to a better overall hold to a limited extent.

The characteristic "ratchet, ratchet" when turning the BOA wheel is almost a ritual. It is a soothing sound that can be categorized somewhere between technology and anticipation. It sounds like stopping, like precision and like: Here we go - ready for the drop-in.

Use

The Salomon Shift Alpha 115 women's ski boot with BOA system was tested under all conceivable conditions. Whether on the ascent or descent, in fresh powder snow in the backcountry, on jumps and sidehits, on the piste, in the park or in steep couloirs - the boot has been part of many snow adventures this season. Whether in spring-like slush at +20 °C or in deep snow at -15 °C - the boot has been part of many snow adventures this season. And the conclusion? The BOA system performed better than me in every situation.

Conclusion

In summary, it can be said that the Salomon Shift Alpha 115 women's ski boot with BOA system is impressive in many areas - especially due to the high level of ease of use and the even adjustment in the lower foot area. It enables quick and precise adjustment of the boot and is superior to classic buckles in this respect. At the same time, the system does not replace all conventional closures and may be more difficult to repair in an emergency. Overall, however, it offers a modern and well thought-out alternative, especially for skiers who value adaptability and ease of use and for whom extra comfort and performance are worth the extra cost of the BOA system.

However, regardless of whether with or without the BOA system - the key to maximum performance remains a ski boot that really fits. Some are blessed here, others - like me - are still on a never-ending search for the perfect fitting model.

But as long as it doesn't quite click, I just keep on turning and enjoy the "ratchet, ratchet" sound.
