I bought these shoes to use as &#34;tennis&#34; shoes (actually playing tennis) and they just won't work for that, at least for me.<br /><br />The main problem is the back of the shoe is *very* low -- I don't wear high-tops or even mid range, but I need a bit of rise on the end so that as I move the shoe stays attached.  These allow my heel to rise out the back even tightly laced, and so just won't work for any kind of strenuous movement (again, for me).<br /><br />I ended up buying the NB 623 ( https://www.amazon.com/gp/product/B007JTXJX0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 ) which DO have a rise at the back and fit me much better.  They also are cheaper, a nice bonus.<br /><br />Everyone's foot is different, and everyone's shoe's needs are, so these might work for you (and Amazon's return policy allows you to try them out).  But overall I'd just pass on these and get the 623.
