The RC4 The Curv One 120 from Fischer will suit advanced level skiers looking for an impressively customisable, higher-volume fit. It has plenty of space internally, without ever becoming overly large; the Vacuum process of custom fitting really improves the feel, removing any pressure spots. The pre-formed 3D liner enhances this further with the heat moulding ensuring a fully customised approach. Somatec puts the skier in a relaxed stance, the chunky 45mm powerstrap boosts the level of control; GripWalk soles boost comfort and safety.Ability LevelOverviewFitAverage around the heel and ankle with a slightly more generous feel on the forefoot and average instep height.Shell Vacuum HV shell, customisable.LinerRC4 The Curv One 120, customisable.Key FeaturesSomatecIn their natural, relaxed position, your feet form a V-shape. In this stance the knees remain parallel when flexed. Fischer took these anatomical facts into account when developing Soma-Tec. The feet remain relaxed in their natural V-position, so knee and ankle joints no longer have to be twisted inward and less strain is placed on the joints. At the same time, edge changes are made easier and energy is transmitted to the ski more accurately.VACUUMVacuum technology uses a unique process and a specially developed high-tech plastic to adapt the shell of the ski boot to the anatomy of any foot. Prior to fitting the plastic of the boots are heated and softened. With the liner inserted, the skier’s foot is placed inside. A special cooling pad is placed around the outside, followed by a compression bag linked to the Vacuum Fit station. The skier then stands on the station in a pre-determined position, this will ensure the boot cools down and shapes to the skier’s natural stance. Once in position, air is pumped into the compression bags, pushing them against the boot and improving the mould being taken of the foot. This procedure achieves a sporty, comfortable fit that is unrivalled in this segment. The heel and ankle area can be expanded or compressed to create best possible shape; the forefoot can be made roomier. Vacu-PlastThis unique material was developed exclusively for use with Fischer ski boots. Apart from its extraordinary moulding properties Vacu-Plast also has other special features: it is very temperature stable, meaning it isn’t adversely affected on extreme cold days when certain plastics become very stiff; it is lighter than other materials used on performance ski boots, and it has better vibration dampening.SpecificationCategory: AlpineFlex: 120Last Width: 101 (+/- 3mm)Custom Shell: YesCustom Liner: YesPower Strap: Velcro 45mmVolume: Medium-HighClips: 4 x GT Aluminium, MicroadjustableSole Unit: Grip Walk (ISO 9523)Pin Inserts: NoHike Mode: NoWeight (g): 1980 (1/2 pair size 26.5)Binding Compatibility: GripWalk, Multi Norm
