Von Miller Gets Awesome Custom Carhartt Boot After Ankle Injury

A season-ending injury can't stop Von Miller from reppin' his favorite brand ... with the Denver Broncos LB getting a sick custom Carhartt walking boot!!

The NFL superstar went down with a devastating ankle tendon injury in the season opener against the Tennessee Titans ... requiring surgery to get back to 100%.

The 31-year-old showed how he's dealing with the bad news on Friday ... revealing a personalized Carhartt boot to help him through the tough time.

Now, Miller's love for the company is the worst kept secret -- the guy LOVES to rep the brand while farming his chickens ... and now he can keep it going during recovery.

It's been pretty positive for the Broncos lately -- Denver just beat the NY Jets on Thursday Night Football to get win #1 on the season.

Seeing Miller have some fun with his injury has to boost the spirits a bit, too.
