Shocking! Captain Reiner's New Boots Stolen by a Mine Rat!

Attention all miners! Captain Reiner's boots (the Type 31 Standard Officer Boots model) went missing during his inspection of Mine Pit No. 1. All miners are to begin searching for them at once!
These boots, of exquisite craftsmanship and distinguished style, are a symbol of Captain Reiner's commitment, and the very foundation of his sure-footedness in the treacherous mine tunnels.
An analysis of the scene indicates the captain was on-site in Mine Pit No. 1, inspecting the mining progress. Yet, a band of lawless mine rats, seizing the opportunity as Captain Reiner removed his boots to cool off, conspired to drag one of these dignified military boots away into the shadows.
This act is nothing less than a flagrant provocation against the Squad! Captain Reiner has always taken exceptional care of his boots, refusing to replace them even once since he began his post in the mines! And now, that noble boot is forced to share its space with these vile rats... Every moment we delay is a further trial on the rats' feeble bodies and minds.
In light of this, we, the mining community, must also take on the responsibility of recovering the boot. Whoever returns it shall be rewarded with ten canteen meatballs. Those who provide useful information shall receive a reward of one to five meatballs, depending on the lead!
