New in box!!  Great boxing shoes, excellent arch support.  This is a men's size 4, or a women's size 6.  Never worn! 

KEEPING THE NIKE HYPERKO STRONG AND LIGHT ARE NIKE FLYWIRE SUPPORTS – HIGH-STRENGTH THREADS THAT WORK LIKE CABLES ON A SUSPENSION BRIDGE WITH SUPPORT ENGINEERED PRECISELY WHERE THE ATHLETE NEEDS IT WHILE BOXING. TO ACCOUNT FOR THE TREMENDOUS TORQUE APPLIED BY BOXERS WHILE PUNCHING, A LOCKDOWN STRAP HAS BEEN PLACED IN THE FOREFOOT AREA. THIS SUPPORT SYSTEM ALLOWS THE NIKE HYPERKO TO BE CONSTRUCTED WITH A SUBSTANTIAL AMOUNT OF MESH WHICH MINIMIZES WEIGHT, AND HELPS WITH VENTILATION AND MOISTURE MANAGEMENT.
