Frequently Asked Questions

• What sets Sidas apart in foot comfort and performance?

  Sidas combines biomechanical research with proprietary materials like Podiaflex® and IonFoam®, plus 3D shaping and FlashFit™ customization, to deliver sport-specific solutions from running to skiing. Their lineup—from Multi+ insoles and 3D sandals to Synergyfit™ socks and ski boot traction—prioritizes alignment, targeted cushioning, and close fit across activities.
• How does FlashFit™ customization work and who benefits from it?

  FlashFit™ is a 10-minute thermoforming process performed with a professional machine that molds Multi+ and select 3D insoles to an individual’s foot shape for targeted arch support and heel stability. Runners, skiers, and anyone with persistent pressure points or fit issues benefit most because the molded shape improves load distribution compared with standard cut-to-fit insoles.
• How do Sidas 3D insoles and Podiaflex® construction improve foot alignment and natural roll?

  The pre-molded 3D geometry supports the medial arch and contours the heel to promote a more natural gait while maintaining flexibility through Podiaflex® bases. Combined with EVA or TXC heel reinforcements, this construction stabilizes the foot without sacrificing ground feel.
• What technologies do Sidas running insoles use to balance cushioning, weight, and propulsion?

  Sidas running insoles pair GEL micro-bubble cushioning in impact zones with lightweight IonFoam® topcovers and thin Podiaflex® bases (models around 45 g) to absorb shock while preserving energy return and ground proximity. That combination reduces vibration at heel strike and delivers a responsive forefoot for more efficient toe-off.
• How do Sidas ski-specific products like the Ski Boot Traction (Black) and Synergyfit™ socks enhance comfort and safety on snow?

  The Ski Boot Traction (Black) features a tapered anti-slip crampon design with adjustable straps and flexible rubber to improve walking traction in ski boots, while Synergyfit™ socks use seamless construction, graduated compression, and variable thicknesses to fine-tune boot volume and warmth. Together they reduce slippage, optimize internal fit, and help maintain control during on- and off-slope movement.
