Premium construction details
Italian Leather & Craftsmanship
Every pair of our common projects slip-on leather sneakers begins with premium full-grain leather sourced from Italian tanneries. We select hides for their natural grain structure and ability to develop a rich patina over time, ensuring your sneakers become more characterful with wear.
The upper is constructed using traditional shoemaking techniques at our Italian factory, where skilled artisans cut and assemble each component by hand. The elasticated side panels are carefully positioned to provide functional stretch while maintaining the shoe’s clean lines. Tonal stitching throughout the design reinforces seams without interrupting the minimalist aesthetic we’re known for.
Sizing & Fit Guidance
Our common projects slip-on leather sneakers follow the brand’s established sizing convention, which typically runs one full size larger than standard US athletic sizing. If you wear a US 10 in running shoes, we recommend ordering a size 41 in these slip-ons. The European sizing ensures a snug, tailored fit consistent with our design philosophy.
The elasticated side goring provides approximately 10mm of stretch on each side, accommodating natural foot width variation while maintaining a secure feel. The shoe should fit close to your foot without pinching, with about 5-8mm of space at the toe. Because full-grain leather molds to your foot shape over the first several wears, initial snugness in width will relax slightly.
Leather Care & Maintenance
Maintaining your common projects slip-on leather sneakers requires minimal intervention. We finish the leather with a light protective coating at the factory, but regular care will preserve appearance and extend lifespan significantly.
Wipe the leather upper with a soft, dry cloth after each wear to remove surface dust and dirt. For deeper cleaning, use a damp cloth with mild soap, then air dry at room temperature away from direct heat sources. Apply a quality leather conditioner every 8-10 wears to replenish natural oils and prevent cracking.

Questions About Our Leather Slip-On Sneakers
Our slip-on sneakers follow the same sizing as the Achilles Low—one full size down from US athletic sizing. The fit is slightly snugger across the instep initially due to the elasticated construction, but the leather stretches to accommodate your foot shape during the break-in period.
If you own Achilles Low sneakers, order the same size in these slip-ons. The elasticated side panels provide similar width accommodation to laced sneakers once broken in.
The full-grain leather upper has natural water resistance and can withstand light rain or brief exposure to wet conditions. However, we don’t recommend wearing them in heavy rain or walking through puddles, as prolonged moisture exposure can damage the leather and affect the interior cushioning.
If your sneakers do get wet, stuff them with newspaper to absorb moisture and allow them to air dry at room temperature for 24-48 hours. Apply leather conditioner once completely dry to restore suppleness.
Most customers experience a 3-5 day break-in period with our common projects slip-on leather sneakers. The full-grain leather will feel stiff initially but softens considerably as it conforms to your foot contours.
We recommend wearing them for 2-3 hours during the first few days, gradually increasing duration as the leather relaxes. The elasticated side panels will also become more supple with wear. By the end of the first week, the sneakers should feel noticeably more comfortable and personalized to your feet.
Clean the Margom sole using a soft brush or cloth with warm water and mild dish soap. Work in circular motions to lift dirt and scuff marks from the rubber surface. For stubborn stains, a melamine foam eraser (magic eraser) effectively removes most discoloration without damaging the sole.
Avoid harsh chemical cleaners, bleach, or abrasive scrubbing pads, as these can break down the vulcanized rubber and cause yellowing. Clean the sole every 5-7 wears to prevent dirt buildup and maintain the white finish.
Yes, after the initial break-in period, our slip-on leather sneakers provide excellent all-day comfort. The cushioned leather footbed molds to your foot shape, and the Margom sole offers good shock absorption for walking on hard surfaces.
The elasticated construction distributes pressure evenly across the instep without creating pressure points. Many customers report wearing them comfortably for 8-10 hours daily once broken in. For maximum comfort, we recommend alternating between pairs to allow the leather to rest and the footbed to decompress between wears.
Wipe your common projects slip-on leather sneakers with a soft, dry cloth after each wear to remove surface dust. For deeper cleaning, use a slightly damp cloth with mild soap, then air dry completely at room temperature.
Apply a quality leather conditioner every 8-10 wears to replenish natural oils and maintain suppleness. This prevents cracking and helps the leather develop an even patina. Store them in the included dust bag when not in use to protect from scratches and light exposure. Avoid storing in direct sunlight or humid environments, as both can damage leather over time.
We source full-grain leather from premium Italian tanneries known for superior hide selection and finishing techniques. This top layer of the hide retains the natural grain structure, making it more durable and breathable than corrected-grain or bonded leathers used in mass-market sneakers.
The leather develops a rich patina over time rather than simply wearing out, meaning your sneakers become more characterful with age. Combined with the hand-assembled construction at our Italian factory and the durable Margom sole, these slip-ons are designed to last for years rather than seasons, justifying the initial investment through exceptional longevity.
