SUPRATUF is a high-abrasion resistant material found exclusively on Supra shoes. (How durable? Tested on the Taber Abrasion meter, which measures the standard in cycles, SUPRATUF is able to withstand more than 200 cycles before abrading. By comparison, suede breaks down in 25 to 40 cycles.) Supra has collaborated with accessory brand HEX to create an iPhone case constructed with the proprietary material used to protect Supra shoes from wear and tear. Available in white or black and adorned with HEX x Supra branding, the iPhone 4/4S case is in stock now at select Supra retailers and online.
