Chinese Drone shop is selling Mavic Pro optional parts from 3rd parties.  Prop Gard is about US$5 and Landing Gear is US$2.  From a practical viewpoint, these might be "you-get-what-you-paid-for" things.

Unfortunately, Store doesn't support English but it seems they deliver international.

Hope it will be available globally soon.

Its all over eBay, just type in "dji mavic prop" and you'll see them. $10.00 free shipping... crap in my opinion.

The landing gear could certainly be useful. Keep the gimbal out of the sand or mud when landing.
I would have made the feet hollow and lighter though. The existing design looks like they could introduce a little bit of unwanted drag.

The front two legs, with the concave design would create drag. Likewise the rear stand has a space which would catch a lot of air as well. The design is not very aerodynamic to say the least.

Why buy a Mavic then? You've given up al the compactness. Might as well buy the P4.

God... How ugly !!

If these things weren't 10 cents plus free shipping I don't think the would sel any of them.l

OMG! That is some precision cutting on the pads for the landing gear extenders! They must have had their 5 year old helping with a scissors. "Hey, let Jimmy cut the pads out!" LOL
