Under Armour and Lapstone & Hammer Celebrate Philly With the UA HB-Lo

As Philadelphia gets ready for MLB All-Star Week, Under Armour and Lapstone & Hammer are teaming up for a limited footwear release built around the city’s movement, energy, and baseball moment.

The collaboration centers on the UA HB-Lo “All Lines Lead Home,” a $130 release that reworks Under Armour’s new basketball-inspired sportswear silhouette through a Philadelphia transit lens. The pair arrives with a fully reflective all-black upper, inspired by the illuminated feel of Philly’s subway tunnels after dark.

That dark base is accented by the signature color system of the city’s transit lines, tying the sneaker back to the larger “All Lines Lead Home” story behind Under Armour’s MLB All-Star Week collection. Graphic mapping details also run down the tongue and insole, serving as a visual reminder that every route eventually leads home.

The release will be supported by a special launch event at Lapstone & Hammer on Sunday, July 12, from 5–7 PM. The event will feature special guests, including King Saladin, along with cocktails, DJs, and pairs available to shop in-store.

The UA HB-Lo “All Lines Lead Home” releases on Sunday, July 12, at 12 PM EST in-store at Lapstone & Hammer and online at lapstoneandhammer.com. A wider release will follow on UnderArmour.com beginning July 14.
