SD Custom Footwear in Chula Vista’s Otay Ranch district is a bespoke shoemaking school and custom-shoe studio founded in 2018 on Otay Lakes Road. The four-day intensive courses blend traditional cobbling techniques with modern sneaker reconstruction, teaching pattern development and exotic-leather stitching at a skill level that parallels the biomechanical focus at Performance Plus Physical Therapy. Each enrolled student receives a personal toolkit, shoe pattern templates, and exotic-leather materials sourced from tanneries including Angelus Direct and Atlantica Leather. Curriculum covers Air Jordan deconstruction, full sole-swap rebuilds, and custom silhouette creation from raw leather panels, attracting alumni who also shop performance footwear at retailers such as Big 5 Sporting Goods. Advanced modules teach Goodyear welt construction, hand-lasted shaping over custom wooden forms, and pigment-layered airbrushing with Angelus acrylic leather paint rated for 180-degree flex without cracking.
