I'm surprised a sport like basketball would allow players to wear apparel which improves their performance using electronics and a motor.


My read was that it'll improve safety and recovery more than enhance performance.


Seems like it could be the same thing, at least that's what McGwire said to himself to justify to himself that it was OK to juice up.

McGwire said he took steroids to get back on the field, sounding much like the Yankees' Andy Pettitte did two years ago, when he admitted using HGH.

"During the mid-'90s, I went on the DL seven times and missed 228 games over five years," McGwire said. "I experienced a lot of injuries, including a ribcage strain, a torn left heel muscle, a stress fracture of the left heel, and a torn right heel muscle. It was definitely a miserable bunch of years, and I told myself that steroids could help me recover faster. I thought they would help me heal and prevent injuries, too."

I was thinking that if it achieves the exact same tightness and fit consistently every time that could be very helpful.

I have no idea about basketball but for mountaineering I sometimes re-lace my boots a few times after putting them on to get the tightness just right in the various places, and the same on both feet.


Coming from someone who doesn't watch any basketball, are there many incidents involving shoes coming off or becoming loose? Is the safety argument real?


This is addressed somewhat in the article:

> Players, for example, will tell you that after about a half hour on the court, their feet will swell, sometimes up to a half size. This changes their comfort level significantly. So they have a choice: either play with their shoes too loose for 30 minutes or tighten them enough to be painful by halftime. Not with an adjustable shoe.


Why not just retie the shoelaces at halftime?


They probably do, but they're already painful by then.


So the safety argument isn't real then. It's a comfort argument.


Misadjusted shoes can cause injury, whether too loose or too tight. It's a safety issue.
