AMENDMENT No. 11 TO SCHEDULE 13D
Item 1.  Security and Issuer.

     This Amendment No. 11 to Schedule 13D relates to the common stock,
par value $.02 per share (the "Common Stock") of The Langer Biomechanics
Group, Inc. (the "Issuer").  The Issuer is a New York corporation with
its principal executive offices located at:  450 Commack Road, Deer Park,
NY 11729.

     Except as expressly stated below, there has been no material change
in any fact or statement made by the above-named persons in the Schedule
13D, filed April 17, 1993, as amended by any of:

     Amendment No. 1, filed February 8, 1995; Amendment No. 2,

     As provided by Rule 13d-2(a) this Amendment No. 11 contains only
material changes to Items to the Schedule 13D, as previously amended.

Item 3.  Source and Amount of Funds or Other Consideration.

     Each of Trigran Investments, L.P., Kenneth Granat and The Granat
Family Limited Partnership (the "Reporting Persons") is filing this
Amendment No. 11 to Schedule 13D.  Each Reporting Person became a member
of a group (as such term is defined in Section 13(d)(3) of the Securities

agreement, dated December 28, 2000, by and among OrthoStrategies, Inc.
("OrthoStrategies"), the Issuer, the Reporting Persons, certain other
shareholders of the Issuer and OrthoStrategies Acquisition Corp.
("Purchaser")  (such agreement being hereinafter referred to as the
"Shareholders Agreement").

     Pursuant to the Shareholders Agreement, OrthoStrategies effected
a cash tender offer (the "Offer") for up to 75% of the issued and
outstanding shares of Common Stock (the "Offer Agreement").  Each
Reporting Person tendered all shares of Common Stock then owned by them
into the Offer.  The Offer Agreement and the Shareholders Agreement
were filed as Exhibits 10.1 and 10.2, respectively, to the Issuer's
Current Report on Form 8-K filed with the Securities and Exchange
Commission on January 5, 2001 (the "Form 8-K").  See Item 6 of Amendment
No. 10 to this Schedule 13D for a more detailed description of the
Shareholders Agreement.

     Purchaser completed the Offer on February 13, 2001, and acquired
all shares of Common Stock owned by each Reporting Person.  Upon
completion of the Offer, Mr. Granat resigned from the Board of Directors
of the Issuer in accordance with a letter agreement, dated December 28,
2000 (the "Resignation Agreement"), a copy of which was filed as Exhibit
10.3 to the Form 8-K.


Item 4.  Purpose of Transaction.

     Not Applicable.

Item 5.  Interest in Securities of the Issuer.

     (a)  No shares of Common Stock (including options to purchase shares
          of Common Stock) of the Issuer are beneficially owned by any
          Reporting Person as of the date of this filing.

     (b)  Not Applicable.

     (c)  Not Applicable.

Item 6.  Contracts, Arrangement, Understandings or Relationships with
         Respect to Securities of  the Issuer.

     Not Applicable.

     1. The Shareholders Agreement (incorporated by reference from
        Exhibit 10.2 to the Form 8-K).
