                              Re: Lock Up Agreement

Gentlemen:

      The  undersigned,  a holder of  common  stock,  par  value  $.02 per share
("Common  Stock"),  or rights to acquire Common Stock or securities  convertible
into  Common  Stock of The  Langer  Biomechanics  Group,  Inc.  (the  "Company")
understands  that  Kanders & Company,  Inc.  ("Kanders & Co.") or an  affiliated
entity and other purchasers  propose to enter into a Tender Offer Agreement (the
"Tender Offer  Agreement")  with the Company  pursuant to which Kanders & Co. or
such affiliated entity and other purchasers will offer to purchase approximately
75% of the issued and  outstanding  shares of Common  Stock of the Company  (the
"Target Shares").

      In order to induce Kanders & Co. or such  affiliated  entity to enter into
the Tender  Offer  Agreement  and to  proceed  with the  purchase  of the Target
Shares,  the  undersigned  irrevocably  agrees  that the  undersigned  will not,
without the prior  written  consent of,  first,  the board of  directors  of the
Company and,  second,  assuming such consent has been  obtained,  the consent of
Kanders  & Co.,  directly  or  indirectly,  make any  offer,  sale,  assignment,
transfer, pledge, hypothecation or other encumbrance, contract to sell, grant of
an  option  to  purchase  or sell or  other  disposition  of or  enter  into any
transaction  or device  designed  to, or which could  reasonably  be expected to
result in the  disposition by any person at any time in the future of any Common
Stock or any securities  convertible  into or exercisable  or  exchangeable  for
Common Stock until the third  anniversary of the date of this Lock Up Agreement,
subject, however, to the immediately succeeding paragraph hereof.

      Upon the  consummation  of any sale of shares of Common Stock by Kanders &
Co.  (other than any such sale or other  disposition  to any  charity,  trust or



foundation, and other than any such sale or other disposition in connection with
the estate planning purposes for Warren B. Kanders,  including,  but not limited
to,  transfers to family  members or trusts for the benefit of family  members),
Kanders & Co.  shall  provide  written  notice  (the  "Kanders  Notice")  to the
undersigned of such sale and the percentage  represented by the number of shares
of Common  Stock  sold by  Kanders & Co. in such sale as  compared  to the total
number of shares of Common  Stock  owned by Kanders & Co.  immediately  prior to
such sale (the "Kanders  Percentage").  Notwithstanding  anything else contained
herein,  if, within 14 days after the date of the Kanders Notice the undersigned
notifies  Kanders & Co. of his  intention to sell up to  percentage of shares of
Common Stock equal to the Kanders  Percentage,  which  notice shall  specify the
exact number of shares to be sold (the "Sale  Notice"),  the  undersigned  shall
sell the number of shares specified in the Sale Notice within the 180 days after
the date of the notice from Kanders & Co.

      The  undersigned  confirms that he understands  that Kanders & Co. and the
Company  will  rely upon the  representations  set  forth in this  Agreement  in
proceeding  with the  purchase  of the Target  Stock.  This  Agreement  shall be
binding  on the  undersigned  and his  respective  successors,  heirs,  personal
representatives and assigns.

                                               Very truly yours,


                                               ________________________________
                                                       Andrew Meyers
