An executive shakeup at Costa Mesa-based Hurley International LLC’s parent company Nike Inc. has left it without a permanent chief executive.

Hurley, a unit of Oregon-based Nike, makes clothes inspired by surfing and skateboarding.

Hurley Chief Executive Jim Calhoun will now step in to lead Massachusetts-based athletic shoe and clothes maker Converse Inc.

The news, announced Thursday, comes less than a month after Calhoun joined Hurley as its chief executive.

Calhoun replaced Roger Wyett at Hurley after Wyett became Nike president of affiliates in February.

Wyett now oversees other company brands, such as Converse and luxury shoe and accessories company Cole Haan.

Wyett, will continue to oversee the various company brands while also acting as interim chief executive at Hurley until a permanent replacement is named.

The new executive appointments at Nike follows the announced retirement of United Kingdom-based Umbro Ltd. Chief Executive Jim Allaker.

Umbro, another unit of Nike, makes soccer gear and clothes.

Former Converse Chief Executive Michael Spillane will now head Umbro.
