NFL Star Joe Haden -- Help from Josh Gordon, Manziel ... For Sneaker Shop Opening

Several Cleveland Browns superstars rallied around their teammate Joe Haden to help him open his new sneaker shop -- from Josh Gordon to Johnny Manziel ... and TMZ Sports has the pics.

As we previously reported, Haden opened "The Restock" in Cleveland last weekend ... a store that specializes in rare sneakers.

A bunch of the Browns showed up when Joe opened the doors ... including Josh Gordon, Donte Whitner and Andrew Hawkins. Cleveland Cavs star Tristan Thompson was also on hand.

And we're told the guys weren't just there to browse -- Josh picked up 3 pairs of Jordans ... so did Tristan Thompson. Hawkins ponied up for a pair of Balenciagas ... which ain't cheap.

Other Browns teammates donated signed jerseys to help decorate the store -- including Johnny Manziel, Brian Hoyer, Phil Taylor and more.
