RC4 110 MV VACUUM BOA

The Fischer RC4 110 MV BOA brings the precision of Fischer's race-derived RC4 line to the piste, combining two worlds of closure: the BOA® H+i1 system on the lower cuff, which wraps the foot with a simple turn of the dial, and 2 micro-adjustable aluminum buckles on the upper cuff, delivering the firm hold demanding skiing requires. The result is a boot that closes in seconds without giving up the precision of a traditional closure where it matters most.

Its VACUUM Fit® shell molds at 80°C and adapts fully to the shape of the foot, eliminating pressure points without losing the direct response that defines the 110 flex. The SOMA-TEC geometry positions the foot in a natural V stance that promotes a smoother, less fatiguing ski, while the GripWalk sole (ISO 23223) and 35 mm velcro strap round out a versatile setup, ready for technical carving on piste as much as for long days of all-round skiing.

TECHNICAL INFORMATION

• BOA® Fit System H+i1 - This is a dial-based closure system that replaces traditional buckles on the boot's lower cuff, tightening evenly via a micro-adjustable steel cable in 0.25 mm increments. Its five-point contact design wraps the foot evenly, reducing peak pressure over the instep by up to 13% compared to a conventional closure. It allows precise on-the-fly adjustments without removing the boot.
• VACUUM Fit® - This is Fischer's proprietary process that molds both the Vacu-Plast shell and the RC4 Vacuum Fit inner liner at 80°C, jointly adapting both elements to the skier's specific foot anatomy. The shell material maintains a predictable, stable flex through temperature changes, while also offering up to 15% less weight than conventional materials. The result is a fully personalized fit from shell to liner that improves the transmission of control impulses.
• GripWalk® (ISO 23223) - This is the sole standard that combines the rolling platform typical of the touring sector with the performance of a traditional alpine sole. Its rounded profile and ribbed co-polymer rubber offer secure grip when walking on slippery surfaces. Compatible with most GripWalk-certified alpine bindings, it does not compromise safety or on-piste performance.
• SOMA-TEC - This is Fischer's proprietary stance geometry that positions the legs in a natural V-shape, with 3.5° of abduction from the heel and 3.5° from the toe. This alignment aims for a more energy-efficient, joint-friendly skiing style, promoting a more natural carving technique. It's built directly into the design of the boot's shell and cuff.
• FISCHER Scan-Fit® - This is the next-generation last developed from the analysis of hundreds of real foot scans collected through the FISCHER Scan-Fit app. This data set allows the last's geometry to be tailored to the actual shape of the average skier's foot, improving power transfer and control from the first use. It works together with the boot's other fit technologies to maximize precision without sacrificing comfort.
