Metatarsal fractures are among the most common foot injuries, caused by direct impact, falls, or repetitive stress. A cast boot immobilizes the foot to prevent the fractured bone from shifting during healing, while the rocker bottom sole allows a more natural gait. Most metatarsal fractures heal within 6–8 weeks in a cast boot.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails style=\"border: 1px solid #e0e0e0; border-radius: 10px; padding: 14px 16px; margin-bottom: 10px;\"\u003e\n\u003csummary style=\"font-weight: bold; font-size: 15px; cursor: pointer; list-style: none;\"\u003eWhat does the pneumatic air bladder do and how do I use it?\u003c\/summary\u003e\n\u003cp style=\"margin: 10px 0 0; font-size: 14px; color: #444;\"\u003eThe integrated pneumatic air bladder applies gentle, even compression around the foot and ankle to control edema (swelling) and improve fit as swelling changes throughout the day.
