Backed by Berkshire Partners, Implus has taken over Spenco Medical Corp.'s insole business and its 2nd Skin medical adhesive line. It will integrate them into its insole business, which comprises the Sof Sole and Sof Comfort brands among others. Implus will also acquire Spenco's Canadian operations. The remaining operations of Spenco are being taken over by its existing management, based in Waco, Texas. Spenco's chief executive, Steve Smith, is retiring. For Implus, the acquisition of Spenco assets is the fifth takeover since Berkshire bought the company in April 2015.
