    • We are looking for a walking boot to help flex and extend the range of motion for my wife who has lost a great deal of the rom in her left foot. Can you lock this boot at a certain degree to help stretch and gradually regain the natural rom by gradually increasing the degrees and locking them to help stretch the tendons.
    • Wink
      This is not considered a Dynamic support. The boot can be locked in certain degrees of plantar and dorsi flexion but will not put an active stretch on the ankle at the same time. The ankle may be passively stretched while in the boot however

    • Can you wash the foam part in the base of the boot? If yes, with what?
    • Hello Joy,

      The liner you can hand wash with mild detergent, the Foam Pad on the base of the boot, I recommend wiping that area with a cleaning wipe.

      Thanks for Contacting Donjoy.

    • Should the heel sit all the way back in the boot?
    • yes, this this is correct, the heel should be all the way back in the boot.

    • can you wash this boot?
    • The Maxtrax liner can be removed and washed in the sinke by hand with lite detergent. Then let it air dry. Be careful when putting the liner back in the boot becuase the velcro on the supports is very aggressive.

    • Hello
      I read the product description and am confused by this statement:
      'Uprights will lock in fixed positions of 0, 7.5, 15, 22.5 and 30 plantar- and dorsi-flexion.'
      Does this mean that this model only locks in these positions or does the piece allow it to move while walking for a fuller range of movement with the protection of an aircast?
      Thank You

    • Hello Ofella,

      You can lock it out in those positions or you can allow for controlled range of motion at those positions. It's very similar to an IROM hinge. For example, you could set it to allow 15 deg of dorsi-flex and 30 deg of plantar flex.
