What role do the silicone and latex inside the shoes play when worn?
A reader whose feet hurt when wearing new shoes due to the hard finish inside became curious about how the actual fit changes after reading the explanation that the inside was reinforced with silicone and latex.
While maintaining the shoe's shape, flexible silicone and leather subsidiary materials are padded instead of hard core materials, and latex is inserted into the insole to reduce the impact transmitted to the feet when walking.
Blanc Sur Blanc's shoes carefully take care of the inside where the foot directly touches, step by step. The entire lining and insole that contact the sole of the foot are wrapped in carefully selected leather to make the touch against the skin soft[1]. In general, leather linings have superior breathability compared to synthetic fibers and are advantageous in absorbing sweat.
The way they support the shape is also distinctive. Ordinary dress shoes usually contain hard and stiff stiffeners to prevent the shoe shape from collapsing, but Blanc Sur Blanc reinforces the inside with non-hard silicone and leather subsidiary materials[2]. This composition helps the shoe move flexibly along the shape of the foot without stiffly resisting when bending and stepping.
Inside the insole that contacts the sole of the foot, latex that relieves impact has been inserted[3]. Highly resilient latex evenly disperses the pressure generated by body weight each time you walk, alleviating the impact transmitted to the ankles and soles of the feet.


The exact thickness of the latex pad and the specific areas where the silicone reinforcement is inserted have not yet been confirmed.
