NEEDLES and PPACO Drop Studded Lux-2 Sliders With Butterfly Branding

The butterfly that made NEEDLES' Papillon tracksuits one of streetwear's most-traded silhouettes now belongs on a slider. The Japanese label partnered with PPACO, the footwear project of veteran shoe designer Toshinosuke Takehara, on the Lux-2 NEEDLES Edition and the Lux-2 NEEDLES Edition With Studs, both of which dropped April 4 exclusively through NEPENTHES. The standard edition came in at ¥19,800 (approximately $124 USD); the studded version at ¥21,780 (approximately $137 USD).

This is the first collaboration between the two brands, and it reads that way in the best sense: nothing here is compromised. PPACO built the Lux-2 around High-PerFORM, a moderately resilient natural latex foam that sits closer to actual ergonomic footwear than to the dense EVA slab at the base of most collab slides. The NEEDLES edition adds a thicker sole profile for additional cushioning and stamps the brand's logo directly into the rubber. The AIR STUDDED SOLE, a registered PPACO technology, embeds air pockets within each surface dot to generate underfoot compression that holds through a full day rather than packing out by noon.

The two silhouettes split cleanly. The standard Lux-2 NEEDLES Edition carries the Papillon butterfly logo on the strap in a restrained placement, smooth molded upper, no additional hardware. The Studs version amplifies that strap with metallic embellishments across its length, pulling the shoe into territory adjacent to punk belt hardware rather than resort sandal. Keizo Shimizu originally drew the butterfly motif from Steve McQueen's tattoo in the 1973 film Papillon; on the Lux-2 strap, it transfers that same DNA into something worn rather than collected.

Both versions come in black and purple. Black is the obvious utility pick, pairing across everything from wide-leg trousers to shorts without asking much of whatever sits above the ankle. Purple is the more interesting call: saturated, specifically NEEDLES, and a colorway that wears better than it photographs because the High-PerFORM material gives it a depth that flat product shots tend to drain out.

For sizing, PPACO's Lux-2 runs in Japanese sizing from 5 (23cm) to 10 (28cm). The High-PerFORM footbed carries just enough give to fit true without the slide you get from softer, spongier alternatives. The contoured arch support means there is no benefit to sizing up; go straight to your standard shoe size.

What these replace is the socks-and-slides combination that streetwear has been running for three years now, doing the styling work without the sock. Worn with wide trousers cropped at the ankle or a resort set, the studded strap is enough to anchor the full look. Sliders have been moving away from post-workout associations for a while; a collab with this much technical specificity in the footbed and this much branding precision in the strap is exactly the kind of release that accelerates that shift. At $124 entry, the NEEDLES Lux-2 competes seriously with slides that charge more for less engineered construction and far less interesting hardware.
