Sierrasocks | SierraSocks.com is a DTC sock retailer offering casual, performance, diabetic, school‑uniform and wholesale styles. Their “Buy 1 = Give 1” model donates a pair for each sold, backed by 1,600+ customer reviews. The site features clear category navigation and strong branding but needs better SEO (missing meta descriptions, H1), richer “About Us” content, improved image alt‑text, and reduced JavaScript reliance for performance and accessibility .
