Surprise Grammy winners Bon Iver have been touring extensively in continued support of their 2011 album, 'Bon Iver, Bon Iver.' The indie folksters have added a handful of dates to their busy schedule this September.

Pitchfork reports that Bon Iver will return to the road on July 5 in Gdynia, Poland and stay overseas for the rest of the summer. The band will then come back to the United States in Providence, R.I. on September 12. They will also include two more Radio City Music Hall dates in New York City, where they already sold out two other previous appearances. See all of the new U.S. dates below.

Frontman Justin Vernon seems to be expanding his business ventures now that he's become more famous. The singer has designed his own kicks for Los Angeles-based shoe company Keep. Pre-orders for the Bon Iver sneakers are being taken now until July 1, and will see a worldwide release this October. Vernon also launched his own record label, called Chigliak, last month.
