The Victor S81 badminton shoes adopt the trend of the knit uppers that are now popular in many other running and athletic shoes. This model is part of Victor’s professional line, which have incorporated several new editions of comfort and fit technologies into the new models for 2017. The new version of EnergyMax offers an increase of rebound and shock protection to make the S81 more responsive and comfortable. The new midsole helps to reduce weight and increase shoe life. The new mesh layer isn’t only stylish, but aids in the superior ventilation of the foot. The outsole has also been upgraded to provide significant increase in slip-resistance.
