The Salomon Sonic 4 ;Balance is a ;lightweight training shoe ;that's designed to be as springy as it is cushioned. Optivibe cushioning dampens uncomfortable vibrations without sacrificing energy return for a truly responsive ride that's revving to go the extra mile.
- Softer mesh and inner bootie construction ;- for even more comfort.
The Sonic 4 ;Balance also features:
- Engineered mesh upper ;- with just the right balance of protection, breathability and foot hold
- OrthoLite Impressions tongue ;- compresses into the shape of your foot over time to create a customised fit
- Internal SensiFit ;- cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customised fit all around the foot
- OrthoLite insole ;- moulded to match your foot's contours and provide superior cushioning, breathability and durability to upgrade the shoe's comfort and performance
- Optivibe midsole ;- a ;combination of foams (one to dampen, one to propel) ;to reduce vibration upon foot strike and therefore decrease muscle fatigue; meanwhile, it delivers a bouncy spring each time you push off the ground
- Geometric Decoupling axis ;- centred to deliver a balanced, effortless forward transit
