The metatarsals — the long bones running from your toes back toward the ankle — sit exposed under thin leather on an ordinary boot. A dropped die, a rolled pipe, or a load slipping off a forklift lands there. An Mt75 guard is rated to absorb a 75-pound-force impact across that whole area.\u003c\/p\u003e\n\u003ch3\u003eWhy Polyurethane, and Why Internal\u003c\/h3\u003e\n\u003cp\u003eThe guard is polyurethane rather than metal, and it sits between the layers of the upper rather than strapped over the lacing. That means it flexes as the boot flexes, adds nothing to the outside profile, and gives you nothing to snag on a ladder rung. For a guard you'll wear every day rather than occasionally, that comfort difference is the whole argument.\u003c\/p\u003e\n\u003ch3\u003eChoose Met Protection From the Start\u003c\/h3\u003e\n\u003cp\u003eA met guard is engineered into the boot's construction and rated as part of the finished product. If your work involves overhead loads, heavy material handling, or anything that can drop on the top of your foot, buy the met-rated boot on day one.\u003c\/p\u003e\n\u003ch2\u003eWhy Choose the CA3594?\u003c\/h2\u003e\n\u003cp\u003eToe and metatarsal protection with an EH rating, in a boot light enough to walk in all day.\u003c\/p\u003e\n\u003ch3\u003eSimilar Styles to Consider\u003c\/h3\u003e\n\u003cp\u003ePrefer an external guard you can see and inspect?

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\u003eInternal or external guard — which should I choose?\u003c\/h3\u003e\n\u003cp\u003eBoth meet Mt75. The internal guard is more comfortable, flexes with the boot, and won't catch on anything. An external guard is easier to inspect and takes direct, repeated abuse better. Choose on the work, not the rating.\u003c\/p\u003e\n\u003ch3\u003eIs the metatarsal guard metal?\u003c\/h3\u003e\n\u003cp\u003eNo. Carolina specifies a polyurethane guard on this style. The toe cap and shank are steel.\u003c\/p\u003e\n\u003ch3\u003eIs the CA3594 waterproof?\u003c\/h3\u003e\n\u003cp\u003eThis Gruntz is an uninsulated, unlined-membrane boot built to breathe. Conditioning the leather a few times a year improves its water resistance. For sustained wet, the CA3593 carries Carolina's sealed SCUBALINER™.\u003c\/p\u003e\n\u003ch3\u003eHow does cement construction affect the boot?\u003c\/h3\u003e\n\u003cp\u003eThe outsole is bonded directly to the upper rather than stitched through a welt, which keeps a met-guard boot lighter and lets it flex from the first day, with no break-in underfoot.\u003c\/p\u003e","brand":"Carolina","offers":[{"title":"8 \/ Medium \/ Dark Brown","offer_id":53230493040913,"sku":"726363747177","price":129.99,"currency_code":"USD","in_stock":false},{"title":"8 \/ Wide \/ Dark Brown","offer_id":53230493073681,"sku":"726363746910","price":129.99,"currency_code":"USD","in_stock":true},{"title":"8.5 \/ Medium \/ Dark Brown","offer_id":48560495952145,"sku":"726363747184","price":129.99,"currency_code":"USD","in_stock":false},{"title":"8.5 \/ Wide \/ Dark Brown","offer_id":48560495984913,"sku":"726363746927","price":129.99,"currency_code":"USD","in_stock":true},{"title":"9 \/ Medium \/ Dark Brown","offer_id":53230493106449,"sku":"726363747191","price":129.99,"currency_code":"USD","in_stock":true},{"title":"9 \/ Wide \/ Dark Brown","offer_id":53230493139217,"sku":"726363747085","price":129.99,"currency_code":"USD","in_stock":true},{"title":"9.5 \/ Medium \/ Dark Brown","offer_id":48560496083217,"sku":"726363747207","price":129.99,"currency_code":"USD","in_stock":false},{"title":"9.5 \/ Wide \/ Dark Brown","offer_id":48560496115985,"sku":"726363747092","price":129.99,"currency_code":"USD","in_stock":true},{"title":"10 \/ Medium \/ Dark Brown","offer_id":53230493171985,"sku":"726363747214","price":129.99,"currency_code":"USD","in_stock":false},{"title":"10 \/ Wide \/ Dark Brown","offer_id":53230493204753,"sku":"726363747108","price":129.99,"currency_code":"USD","in_stock":true},{"title":"10.5 \/ Medium \/ Dark Brown","offer_id":48560496247057,"sku":"726363747221","price":129.99,"currency_code":"USD","in_stock":false},{"title":"10.5 \/ Wide \/ Dark Brown","offer_id":48560496279825,"sku":"726363747115","price":129.99,"currency_code":"USD","in_stock":true},{"title":"11 \/ Medium \/ Dark Brown","offer_id":53230493237521,"sku":"726363747238","price":129.99,"currency_code":"USD","in_stock":false},{"title":"11 \/ Wide \/ Dark Brown","offer_id":53230493270289,"sku":"726363747122","price":129.99,"currency_code":"USD","in_stock":true},{"title":"11.5 \/ Medium \/ Dark Brown","offer_id":48560496378129,"sku":"726363747245","price":129.99,"currency_code":"USD","in_stock":false},{"title":"11.5 \/ Wide \/ Dark Brown","offer_id":48560496410897,"sku":"726363747139","price":129.99,"currency_code":"USD","in_stock":true},{"title":"12 \/ Medium \/ Dark Brown","offer_id":53230493303057,"sku":"726363747252","price":129.99,"currency_code":"USD","in_stock":false},{"title":"12 \/ Wide \/ Dark Brown","offer_id":53230493335825,"sku":"726363747146","price":129.99,"currency_code":"USD","in_stock":true},{"title":"13 \/ Medium \/ Dark Brown","offer_id":53230493368593,"sku":"726363747269","price":129.99,"currency_code":"USD","in_stock":false},{"title":"13 \/ Wide \/ Dark Brown","offer_id":53230493401361,"sku":"726363747153","price":129.99,"currency_code":"USD","in_stock":true},{"title":"14 \/ Medium \/ Dark Brown","offer_id":53230493434129,"sku":"726363747276","price":129.99,"currency_code":"USD","in_stock":true},{"title":"14 \/ Wide \/ Dark Brown","offer_id":53230493466897,"sku":"726363747160","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1107\/6454\/files\/CLA-001-CA3594.jpg?v=1753306518","url":"https:\/\/www.overlookboots.com\/es\/products\/carolina-mens-gruntz-6-st-internal-metguard-work-boot-brown-ca3594","provider":"Overlook Boots","version":"1.0","type":"link"}
