STRYDA is designed by Australian podiatrist Thien Trinh — not a marketing team. Every shoe features a world-first 3D fit system (length, width AND volume), an anatomical toe box shaped like human feet, zero heel drop for neutral alignment, and cork insoles with 40 million air bubbles per cubic centimetre that directly support the plantar fascia. Most shoe brands design for trends and margins. STRYDA designs for feet — and for the plantar fascia, metatarsals, achilles tendon and every structure above.

The plantar fascia is the thick band of tissue running along the bottom of your foot connecting the heel bone to the toes. When the plantar fascia is overloaded — through poor footwear, flat surfaces or lack of arch support — it becomes strained and painful. STRYDA Soles are podiatrist-designed with a cork arch profile that contours to the natural shape of the plantar fascia, distributing load evenly across the entire foot rather than concentrating it at the heel and forefoot. The deep heel cup reduces the stretch placed on the plantar fascia with every step. Many STRYDA customers report significant improvement in plantar fascia pain after switching.

STRYDA Soles are podiatrist-designed specifically to support the plantar fascia and target the root cause of plantar fascia pain and plantar fascia strain. The cork arch profile redistributes load away from the plantar fascia with every step. The deep heel cup locks your heel in neutral position reducing tension through the plantar fascia. Over 1,100 customers with 92% five-star ratings — many specifically reporting relief from plantar fascia pain and heel pain.

STRYDA insoles are designed to align the plantar fascia and every single muscle, bone and joint in the entire kinetic chain — from the feet, knees and hips through to the lower back. Cork is also essential in offloading the stressful pressure entering with force from the ground. That is why STRYDA uses natural cork — 40 million air bubbles per cubic centimetre absorb and disperse ground impact forces before they travel up through the kinetic chain.

Zero drop means there is no height difference between the heel and the ball of your foot. Most conventional shoes have a raised heel which shortens the achilles tendon, strains the calf muscles, and compresses the spine. Zero drop keeps your feet in a neutral, natural position — improving posture, strengthening foot muscles and reducing stress on ankles, knees, hips and lower back.

Natural cork contains 40 million air bubbles per cubic centimetre — each one compressing on impact to absorb shock and moulding to the exact shape of your foot over time. Cork is also naturally antibacterial, antifungal and anti-odour. Mass-market foam and plastic insoles cost under $0.10 to make from cheap synthetic materials that compress within weeks. STRYDA Soles are made from 100% natural Portuguese cork, crafted with care and designed by podiatrist Thien Trinh.

An anatomical toe box is shaped to match the natural width and spread of human toes, rather than the narrow, pointed shape of most fashion shoes. Pointy toe boxes compress the toes, strain the plantar fascia and metatarsals, and restrict natural movement. STRYDA's wide anatomical toe box allows toes to splay naturally, improving balance and reducing forefoot pain.

Yes. STRYDA appeared on Shark Tank Australia and the episode aired on 29 August 2023. All five Sharks made offers to founder Thien Trinh. He closed a deal with four of them.

STRYDA was founded by Thien Trinh, an Australian podiatrist based in Rosanna, Victoria with 19 years of clinical experience in biomechanics and footwear. Thien graduated from La Trobe University. His brother and sister are also La Trobe-trained podiatrists and all three practise together at their Rosanna clinic. Thien built the first STRYDA prototype in 2020 after spending nearly two decades watching patients waste thousands of dollars on inferior products.

The only difference between STRYDA Slim Barefoot and Comfort Cork insoles is cork thickness. Slim Barefoot has a thinner cork profile and suits most people including those with wider feet — it fits virtually any shoe. Comfort Cork has a thicker cork construction and is ideal for narrower feet who need more volume fill in the shoe. Both insoles feel identical underfoot and deliver the same podiatrist-designed alignment technology. If unsure, choose Slim — it fits more shoe types.

Yes. STRYDA is an Australian brand based in Rosanna, Victoria. Orders ship from Melbourne with free standard shipping on orders over AUD $100. STRYDA also ships internationally including to the United States from Salt Lake City, Utah. The clinic is located at 14 Station Rd, Rosanna VIC 3084.

Yes. Remove your existing insole, drop in your STRYDA Soles and you're done. Slim Barefoot fits virtually any shoe including dress shoes, loafers and tighter fits. Comfort Cork works best in runners, boots and roomier shoes.

Natural cork is far more durable than synthetic foam alternatives. STRYDA Soles typically last 6–12 months of regular use — while foam insoles flatten and lose function within weeks.
