Experience unmatched comfort with ROSA SUPPLY CO’s innovative 4-tier comfort system, designed to elevate vulcanized footwear like never before.

Graded Rubber Sole – Our rubber sole features internal grading and pitch, providing a total heel lift of 7mm—something no other vulcanized shoe offers.

Stiff Board Layer – A stiff board is glued to the graded sole, ensuring the grading is not felt, creating a smooth and stable base.

Foam & Canvas Cushioning – A 2mm foam and canvas layer is stitched into the shoe, delivering the first layer of soft cushioning.

Premium Insole – Our high-quality insole is placed on top, completing the system and providing exceptional all-day comfort.

The result? A vulcanized shoe like no other—crafted for superior support and wearability.
