Strongsize
October 2026
Strongsize has a clear fit story and credible customer proof. The research points to avoidable friction in landing destinations, mobile rendering and the final steps toward purchase. These ideas make the promised products easier to find and the purchase path easier to complete.
What we want to test
WaffleFlex Availability
The audit found this product sold out, but a live check now shows some variants are buyable while others remain unavailable. A shopper whose size is unavailable still reaches a Notify Me state. Show available options clearly and verify the paid destination against the promoted size and color before rerouting traffic.
The unavailable selection gives way to a clear route to buyable options. Concept illustration only. Final design will differ.
T-Shirt Landing Page
Traffic promised the Everyday Stretch Tee and Long Sleeve reaches a broad T-Shirts collection showing 24 of 41 products. Shoppers must find the two promoted styles within the wider assortment. Test a focused page that presents those two styles with a direct action for each.
The full assortment becomes a focused two-style choice. Concept illustration only. Final design will differ.
PDP Image Loading
The September 29 mobile audit measured a 47.9-second largest contentful paint on the Everyday Stretch PDP. The product image is central to judging fit, so a late visual delays that decision. Test the same buy box with the primary image visible sooner.
The product photo appears promptly beside the unchanged buy box. Concept illustration only. Final design will differ.
Homepage Hero Loading
The September 29 mobile audit measured a 24.4-second largest contentful paint on the homepage. That delays the campaign visual and its shopping actions for mobile visitors. Test the same hero experience with the image and actions available sooner.
The football-field hero and shopping actions appear together sooner. Concept illustration only. Final design will differ.
Sticky Add to Cart
The captured PDP requires a size selection and then continues into a long education section without a persistent purchase action. A shopper reading below the buy box must return to it to add the product. Test a compact bar that keeps the selected item, price and Add to Cart action in reach.
A compact purchase bar follows the selected item below the buy box. Concept illustration only. Final design will differ.
Cart Cross-Sell
The captured cart drawer shows one item and checkout actions, while the PDP already shows a Complete the look module. That complementary choice disappears at the cart step. Test one relevant product tile inside the drawer, with the existing cart actions retained.
A complementary item appears below the cart line item. Concept illustration only. Final design will differ.
Fit Guarantee in Buy Box
The 30-Day Fit Guarantee appears on the homepage and dedicated landing page, but the captured PDP buy box shows only the review summary near size selection. The fit promise is less visible where shoppers choose their size. Test the same guarantee immediately above Add to Cart.
The existing fit promise moves into the size decision area. Concept illustration only. Final design will differ.
Fit-Matched Testimonials
The standard PDP still shows only an aggregate review count near the buy box. The September audit captured named height-and-size proof on a dedicated landing page, but the latest check did not find that format on the reviewed fit guide or listicle pages. Test a short, verified testimonial strip directly below the purchase controls.
Named, size-specific proof appears below the purchase controls. Concept illustration only. Final design will differ.
Biggest Killers of Conversion Rate
- Some promoted size and color combinations lead to an unavailable state, and broad collection landing pages make shoppers search again.
- Mobile page rendering was slow in the September 29 audit, especially on the product page.
- Fit is the reason customers buy, yet reviews also report length misses and inconsistent fit within packs.
- The guarantee, body-specific proof and complementary products are present elsewhere on the site but less visible at key purchase steps.
