{"product_id":"viktos-ptxf-core-2-shoe-dark-navy","title":"VIKTOS - PTXF Core 2 Shoe | Dark Navy","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe VIKTOS PTXF Core 2 is a purpose-built training shoe for fitness-focused individuals who want performance underfoot without the bulk. The lightweight engineered mesh upper keeps things breathable across long sessions, while reinforced synthetic leather overlays add durability and lateral stability in the areas that take the most punishment. A fitness-focused 4mm heel-to-toe drop keeps the foot in a natural position across cardio, strength work, and daily wear.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe mid-volume forefoot is slightly tighter than the first-generation Core shoe to cradle the foot during heavy lifts, while still allowing natural foot splay under load. The mobility bottom unit is engineered for traction, cushioning, and stability - enough to handle daily cardio without sacrificing ground feel for strength training. A solid all-day option that transitions from gym to street without missing a beat.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eFeatures\u003c\/h4\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLightweight Engineered Mesh Upper:\u003c\/strong\u003e Breathable chassis that balances support and airflow - keeps weight down without compromising structure across training and daily wear.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eReinforced Synthetic Leather Overlays:\u003c\/strong\u003e Added durability and lateral stability at primary wear areas for long-term performance under training loads.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMobility Bottom Unit:\u003c\/strong\u003e Engineered for traction, cushioning, and stability - suited to gym floor, cardio, and strength training without sacrificing ground feel.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMid-Volume Forefoot:\u003c\/strong\u003e Slightly reduced volume from the first-generation Core shoe for a more cradled fit during heavy lifts, while still allowing natural foot splay under load.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFitness-Focused 4mm Heel-to-Toe Drop:\u003c\/strong\u003e Low drop promotes a natural foot position across training disciplines and extended daily wear.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eSpecifications\u003c\/h4\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Dark Navy\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eToe:\u003c\/strong\u003e Soft toe\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eUpper:\u003c\/strong\u003e Lightweight engineered mesh with reinforced synthetic leather overlays\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eOutsole:\u003c\/strong\u003e Mobility bottom unit (traction, cushioning, stability)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHeel to Toe Drop:\u003c\/strong\u003e 4mm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year workmanship and materials\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VIKTOS","offers":[{"title":"8.5","offer_id":44281086509225,"sku":"VIKTOS-1008103","price":143.0,"currency_code":"USD","in_stock":false},{"title":"9","offer_id":44281086541993,"sku":"VIKTOS-1008104","price":143.0,"currency_code":"USD","in_stock":true},{"title":"11.5","offer_id":44281086738601,"sku":"VIKTOS-1008109","price":143.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/9374\/4297\/files\/VIKTOS-PTXFCore2Shoe_DarkNavy.png?v=1752636802","url":"https:\/\/www.tacsource.us\/products\/viktos-ptxf-core-2-shoe-dark-navy","provider":"TacSource","version":"1.0","type":"link"}
