The Forged Rubber™ Sneakers are the best city sneakers in the world. They're made by hand, one at a time, on 70-year-old machines Chrome salvaged from Slovakia. The rubber is harvested from nearby rubber tree farms, fused directly on to Chrome's 12 oz canvas upper at 300 degrees Fahrenheit, and will not delaminate - event at the flex point. Chrome added their signature reflective heel and an antimicrobial sock liner with quick dry contoured footbed for sockless summers and the occasional river crossing. Forged Rubber™ Sneakers look like sneakers, built like army boots.
- Forged Rubber™ sole fused directly onto the upper at 300 degrees Fahrenheit and 30psi for superior durability
- 12 oz fire hose canvas uppers for durable breathable comfort
- signature reflective heel for night visibility
- antimicrobial sock liner for odor resistance and wearing without socks
- contoured impact-resistant PU footbed for all day comfort
The Forged Rubber™ technology is the most durable way to attach a rubber sole to an upper. Fusing the sole directly to the upper to produce a more flexible, comfortable feel.
Chrome Forged Rubber™ sneakers are made with DESMA vulcanization machines. DESMA was founded in Germany in 1946 and at one point was responsible for making over 90% of the European safety shoes and boots. DESMA vulcanization machines are the size of a small dishwasher. It takes 10 minutes to make each shoe using heat at 300 degrees Fahrenheit and pressure, fusing the rubber sole directly to the upper. DESMA vulcanization machines have since been replaced with more modern and efficient autoclave vulcanization that batch process parts, but produce a less durable product. Chrome's Forged Rubber™ process is slower than the modern vulcanization processes and more hands on. A pair of shoes is made side by side on one machine each (left and right) while modern autoclave vulcanization requires the shoes to be passed down a production line through multiple steps.
Rubber Tree Harvesting
Natural Rubber is harvested in the form of latex. On a Rubber Tree Farm the trees grow to be as tall as 80 feet. Harvesters make a small thin incision in the form of a half downward spiral on the tree's bark, cutting through its latex vessels. The incision creates a spiral flow of latex from the tree which is collected in small buckets. If the tapping process is done correctly these trees can produce latex for up to 5 years.
