TECHNICAL FIELD
The present disclosure relates generally to protective and supportive athletic gear and methods of making the same. The present disclosure relates to devices and methods of supporting a wearer's ankle, such as ankle straps and ankle braces. More particularly, the present disclosure relates to ankle braces having ankle stays for providing medial/lateral ankle support.
BACKGROUND
Each year, many people, both athletes and non-athletes, suffer ankle injuries. In some cases, athletes wrap their ankles with adhesive tape in an attempt to prevent ankle injuries and/or to support their ankles after an injury has occurred. In many instances, athletes and others use ankle braces to protect and/or to rehabilitate their ankles.
Devices for supporting or stabilizing the foot or ankle of a wearer may be worn by a wearer for everyday use and/or for use when engaging in physical activity. Injuries to the foot or ankle are common and may affect a wearer's physical ability and/or athletic performance. For certain wearers it may be beneficial to use an artificial structure to support a foot or ankle that has been weakened or injured. Certain rigid structures may be worn through the day and/or when engaging in sports to provide structural support, or prevent further injury. Often a physician or healthcare worker may apply a custom fitted support or structure to the outside of wearer's limb to provide weight bearing support to the wearer's limb.
While a variety of ankle braces are known, there is a desire for continued improvement in the performance and comfort of known ankle braces. Certain support structures for the foot or ankle of a wearer, such as straps or braces, are available and may provide certain advantages such as agility, comfort, or weight bearing capabilities. However, certain options may be unsuitable because of particular characteristics. For example, sleeves that are currently available may be flexible or comfortable, but may not provide adequate support. In other instances, a custom fitted device may be costly and/or require extensive customization for a wearer. Additionally, certain devices that provide structural support may be uncomfortable, or unsuited for use in certain sports that require a particular level of agility or movement by the wearer's limbs. There is thus a need for a device or method for supporting a limb or limbs of a wearer that provides suitable weight bearing capability yet is flexible and comfortable enough to be used during sports and is also cost effective and accessible.
