basketball strength training shoes products for sale | eBay。Like new No real signs of wear Original black and red model Does not come with training DVD, laminated training card, and stretch strap for pre/post workout stretching \"The front half of the shoe’s footprint is enlarged for support, balance, and shock absorption. This allows you to work your calves and Achilles tendons without risking injury to your ankles or knees. As you run, lift, jump, and move throughout your workout, your heels will dip below your toes, stretching the calves and forcing them to engage. Wearing these shoes when you’re training can increase your jump height by between 5 and 10 inches. They can make you faster, too. Wearing them could shave up to 2/10ths of your 40-yard dash without any additional speed training when you run. That may not sound like a lot, but when you look at what it translates into on longer distances, you’d be taking over 8 seconds off of your mile and over 27 seconds off of your 5K time. That’s a significant amount of time for anyone training for a new personal record.\" I AM NOT HELD ACCOUNTABLE OR LIABLE FOR ANY INJURIES SUSTATINED WHILE WEARING THESE.
