Rocky Brands will close the Boston office it obtained with the acquisition of Honeywell International’s lifestyle footwear business that includes the Xtratuf and Muck brands, and cut its non-manufacturing headcount by approximately 13 percent. The actions are expected to result in $3.0-$4.0 million in annualized savings for the company that will take a one-time severance charge of $1.0 million in the second quarter related to the staff cuts.
