It's also slow and expensive to make — which is why you find it on boots built to be resoled two or three times rather than replaced.\u003c\/p\u003e\n\u003ch3\u003eBuilt for Heat\u003c\/h3\u003e\n\u003cp\u003eAn ordinary rubber outsole softens and eventually delaminates on hot surfaces. A Vibram® heat-resisting compound holds its structure, and the neoprene midsole behind it does the same. A stitched welt won't let go under heat the way a glued bond can. Every layer of this boot is chosen with the same problem in mind.\u003c\/p\u003e\n\u003ch3\u003eWhat a Metatarsal Guard Actually Protects\u003c\/h3\u003e\n\u003cp\u003eA safety toe covers the toes and nothing else. The metatarsals — the long bones running from your toes back toward the ankle — sit exposed under thin leather on an ordinary boot. An Mt75 guard is rated to absorb a 75-pound-force impact across that whole area. The external guard here can be inspected after every hit.\u003c\/p\u003e\n\u003ch2\u003eWhy Choose the CA521?\u003c\/h2\u003e\n\u003cp\u003eUnion-built, resoleable, heat-resisting, with steel-toe and Mt75 metatarsal protection — a boot made to be repaired rather than thrown away.\u003c\/p\u003e\n\u003ch3\u003eSimilar Styles to Consider\u003c\/h3\u003e\n\u003cp\u003eWant a broad toe box on a similar heat-resisting external metguard platform?

An all-around Goodyear welt stitches the outsole to the upper around the full perimeter, so a cobbler can cut the stitching, replace the sole, and re-stitch it. This is the construction that lets a boot outlast several soles.\u003c\/p\u003e\n\u003ch3\u003eWhat does the Mt75 rating mean?\u003c\/h3\u003e\n\u003cp\u003eIt is the ASTM F2413 metatarsal impact classification. The guard is tested to withstand a 75-pound-force impact across the top of the foot — the same energy threshold used for the I\/75 toe rating, applied to a different part of the boot.\u003c\/p\u003e\n\u003ch3\u003eWhat does a heat-resisting outsole actually do?\u003c\/h3\u003e\n\u003cp\u003eIt resists softening and breaking down on hot surfaces, where a standard rubber compound would deform and separate. It is not a rating for walking through fire or standing in molten metal — it extends the life of the sole in hot work.\u003c\/p\u003e\n\u003ch3\u003eWhere is the CA521 made?\u003c\/h3\u003e\n\u003cp\u003eIn Carolina's Martinsburg, Pennsylvania factory, by members of UFCW Local 1776 Keystone State. It is made in the USA with global parts.\u003c\/p\u003e\n\u003ch3\u003eIs the CA521 EH rated?\u003c\/h3\u003e\n\u003cp\u003eYes. It's electrical hazard rated, tested to withstand up to 18,000 volts at 60Hz for one minute without leakage.\u003c\/p\u003e\n\u003ch3\u003eHow does the CA521 fit?\u003c\/h3\u003e\n\u003cp\u003eIt runs true to size — order the size you wear in athletic shoes, and choose Wide if you normally need an EE width. The removable Ortholite footbed and EVA cushioned insole resist packing out, and the neoprene midsole absorbs shock.\u003c\/p\u003e","brand":"Carolina","offers":[{"title":"8 \/ Medium \/ Black","offer_id":53229881983249,"sku":"726363766529","price":324.99,"currency_code":"USD","in_stock":true},{"title":"8 \/ Wide \/ Black","offer_id":53229882016017,"sku":"726363766413","price":324.99,"currency_code":"USD","in_stock":true},{"title":"8.5 \/ Medium \/ Black","offer_id":53221746901265,"sku":"726363766536","price":324.99,"currency_code":"USD","in_stock":true},{"title":"8.5 \/ Wide \/ Black","offer_id":53221746934033,"sku":"726363766420","price":324.99,"currency_code":"USD","in_stock":true},{"title":"9 \/ Medium \/ Black","offer_id":53229882048785,"sku":"726363766536","price":324.99,"currency_code":"USD","in_stock":true},{"title":"9 \/ Wide \/ Black","offer_id":53229882081553,"sku":"726363766420","price":324.99,"currency_code":"USD","in_stock":true},{"title":"9.5 \/ Medium \/ Black","offer_id":52137075474705,"sku":"726363766543","price":324.99,"currency_code":"USD","in_stock":true},{"title":"9.5 \/ Wide \/ Black","offer_id":52137075507473,"sku":"726363766437","price":324.99,"currency_code":"USD","in_stock":true},{"title":"10 \/ Medium \/ Black","offer_id":53229882114321,"sku":"726363766550","price":324.99,"currency_code":"USD","in_stock":true},{"title":"10 \/ Wide \/ Black","offer_id":53229882147089,"sku":"726363766444","price":324.99,"currency_code":"USD","in_stock":true},{"title":"10.5 \/ Medium \/ Black","offer_id":52137075605777,"sku":"726363766567","price":324.99,"currency_code":"USD","in_stock":false},{"title":"10.5 \/ Wide \/ Black","offer_id":52137075638545,"sku":"726363766451","price":324.99,"currency_code":"USD","in_stock":true},{"title":"11 \/ Medium \/ Black","offer_id":53229882179857,"sku":"726363766574","price":324.99,"currency_code":"USD","in_stock":true},{"title":"11 \/ Wide \/ Black","offer_id":53229882212625,"sku":"726363766468","price":324.99,"currency_code":"USD","in_stock":true},{"title":"11.5 \/ Medium \/ Black","offer_id":52137075736849,"sku":"726363766581","price":324.99,"currency_code":"USD","in_stock":true},{"title":"11.5 \/ Wide \/ Black","offer_id":52137075769617,"sku":"726363766475","price":324.99,"currency_code":"USD","in_stock":true},{"title":"12 \/ Medium \/ Black","offer_id":53229882245393,"sku":"726363766598","price":324.99,"currency_code":"USD","in_stock":true},{"title":"12 \/ Wide \/ Black","offer_id":53229882278161,"sku":"726363766482","price":324.99,"currency_code":"USD","in_stock":true},{"title":"13 \/ Medium \/ Black","offer_id":53229882310929,"sku":"726363766611","price":324.99,"currency_code":"USD","in_stock":true},{"title":"13 \/ Wide \/ Black","offer_id":53229882343697,"sku":"726363766505","price":324.99,"currency_code":"USD","in_stock":true},{"title":"14 \/ Medium \/ Black","offer_id":53229882376465,"sku":"726363766628","price":324.99,"currency_code":"USD","in_stock":false},{"title":"14 \/ Wide \/ Black","offer_id":53229882409233,"sku":"726363766512","price":324.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1107\/6454\/files\/CLA-001-CA521.jpg?v=1757560479","url":"https:\/\/uverlookboots.com\/products\/carolina-mens-int-6-steel-toe-met-guard-wedge-work-boot-black-ca521","provider":"Overlook Boots","version":"1.0","type":"link"}
