US outerwear maker Timberland has confirmed it is recalling around 193,000 pairs of steel toe boots because they may not provide enough protection.

No injuries have been reported, but the company says its PRO Direct Attach Steel Toe Boots "could fail to provide the intended protection against compression and impact, posing the risk of a foot injury to consumers."

The boots were sold at shoe stores and other independent retailers in the US from September 2005 through September 2007, for between US$90 and $115. They were manufactured in the Dominican Republic.

Direct Attach Steel Toe boots made in China, meanwhile, were not subject to the recall, Timberland said.

Consumers have been told to stop wearing the recalled boots immediately and contact The Timberland Company to receive a free replacement pair of boots.

Timberland last week revealed that the voluntary recall would cost the company $4m and contribute to a narrowed full year outlook.
