i just received this pair a day ago i had a volleyball session this afternoon. I could proudly say that this stuff is just absolutely great and highly recommend for volleyball player, especially high jumper. Many people say that they have an uncomfortable experience at the toe box, which is very narrow. However i strongly believe that this design is just perfectly fit for narrow foot, for heavy and quick movement because it can effectively and securely wrap your foot while also maintaining comfort. For high jumper, the insole, which is the mixture of lightstrike and repetitor, is awesome. You may notice that the cushion of the forefoot is not as soft as other insole tech such as boom or zoom foam, however, it is a great balance of cushioning, lateral stability and ground sensation, perfectly designed for different type of indoor sport from badminton to handball, but strongly recommended for volleyball. One little cons but might be one of the most major improvement in the next generation is, i believe, the carbon plate technology. For torsional resistance and massive energy return, especially important for quick and high jump, a full length carbon plate or carbon shank could put the experience of this shoes to a higher level. To wrap up, at this price, with tight budget, this is absolutely the best choice for indoor sport, no doubt at all.
