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.\u003c\/p\u003e\n\u003ch3\u003eA Linesman Shank Is Not an Ordinary Shank\u003c\/h3\u003e\n\u003cp\u003eA linesman shank is heavier and stiffer than the shank in a standard work boot, built so you can stand with your full weight on a narrow rung or a pole step without the arch collapsing.

For standing still in deep cold, look to 600g and above; for milder conditions, an uninsulated boot breathes better.\u003c\/p\u003e\n\u003ch3\u003eCan the CA7921 be resoled?\u003c\/h3\u003e\n\u003cp\u003eYes. Welt construction stitches the lug outsole to the upper rather than bonding it, so a cobbler can replace it when the tread wears down.\u003c\/p\u003e\n\u003ch3\u003eWhy a composite toe on an insulated boot?\u003c\/h3\u003e\n\u003cp\u003eSteel conducts heat away from your toes, so a steel-toe insulated boot goes cold at the cap first no matter how much Thinsulate™ sits behind it. A composite cap doesn't.\u003c\/p\u003e\n\u003ch3\u003eWhat safety standards does the CA7921 meet?\u003c\/h3\u003e\n\u003cp\u003eThe composite toe meets ASTM F2413 I\/75 C\/75, Carolina rates the internal metguard to ASTM F2413 Mt75, and the boot is EH rated, tested to 18,000 volts at 60Hz for one minute without leakage.\u003c\/p\u003e\n\u003ch3\u003eHow does the CA7921 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. With 400g of insulation it runs warm, so try it on in the socks you work in; the internal metguard flexes with the foot, and the AG7 footbed is removable.\u003c\/p\u003e","brand":"Carolina","offers":[{"title":"8 \/ Wide \/ Brown","offer_id":53230701052177,"sku":"726363501465","price":264.99,"currency_code":"USD","in_stock":true},{"title":"8 \/ Extra Wide \/ Brown","offer_id":53230701084945,"sku":"726363503186","price":264.99,"currency_code":"USD","in_stock":false},{"title":"8.5 \/ Wide \/ Brown","offer_id":45073282892049,"sku":"726363501472","price":264.99,"currency_code":"USD","in_stock":true},{"title":"8.5 \/ Extra Wide \/ Brown","offer_id":45073284497681,"sku":"726363503193","price":264.99,"currency_code":"USD","in_stock":false},{"title":"9 \/ Wide \/ Brown","offer_id":53230701117713,"sku":"726363501489","price":264.99,"currency_code":"USD","in_stock":true},{"title":"9 \/ Extra Wide \/ Brown","offer_id":53230701150481,"sku":"726363503209","price":264.99,"currency_code":"USD","in_stock":true},{"title":"9.5 \/ Wide \/ Brown","offer_id":44466023629073,"sku":"726363501496","price":264.99,"currency_code":"USD","in_stock":false},{"title":"9.5 \/ Extra Wide \/ Brown","offer_id":44466023661841,"sku":"726363503216","price":264.99,"currency_code":"USD","in_stock":false},{"title":"10 \/ Wide \/ Brown","offer_id":53230701183249,"sku":"726363501502","price":264.99,"currency_code":"USD","in_stock":true},{"title":"10 \/ Extra Wide \/ Brown","offer_id":53230701216017,"sku":"726363503223","price":264.99,"currency_code":"USD","in_stock":false},{"title":"10.5 \/ Wide \/ Brown","offer_id":44466023760145,"sku":"726363501519","price":264.99,"currency_code":"USD","in_stock":true},{"title":"10.5 \/ Extra Wide \/ Brown","offer_id":44466023792913,"sku":"726363503230","price":264.99,"currency_code":"USD","in_stock":false},{"title":"11 \/ Wide \/ Brown","offer_id":53230701248785,"sku":"726363501526","price":264.99,"currency_code":"USD","in_stock":true},{"title":"11 \/ Extra Wide \/ Brown","offer_id":53230701281553,"sku":"726363503247","price":264.99,"currency_code":"USD","in_stock":false},{"title":"11.5 \/ Wide \/ Brown","offer_id":44466023891217,"sku":"726363501533","price":264.99,"currency_code":"USD","in_stock":true},{"title":"11.5 \/ Extra Wide \/ Brown","offer_id":44466023923985,"sku":"726363503254","price":264.99,"currency_code":"USD","in_stock":false},{"title":"12 \/ Wide \/ Brown","offer_id":53230701314321,"sku":"726363501540","price":264.99,"currency_code":"USD","in_stock":true},{"title":"12 \/ Extra Wide \/ Brown","offer_id":53230701347089,"sku":"726363503261","price":264.99,"currency_code":"USD","in_stock":false},{"title":"13 \/ Wide \/ Brown","offer_id":53230701379857,"sku":"726363501557","price":264.99,"currency_code":"USD","in_stock":true},{"title":"13 \/ Extra Wide \/ Brown","offer_id":53230701412625,"sku":"726363503278","price":264.99,"currency_code":"USD","in_stock":false},{"title":"14 \/ Wide \/ Brown","offer_id":53230701445393,"sku":"726363501564","price":264.99,"currency_code":"USD","in_stock":true},{"title":"14 \/ Extra Wide \/ Brown","offer_id":53230701478161,"sku":"726363503285","price":264.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1107\/6454\/files\/CLA-001-ca7921.jpg?v=1762529776","url":"https:\/\/uverlookboots.com\/products\/carolina-mens-metpro-crazy-hardrock-8-comp-toe-wp-work-boot-brown-ca7921","provider":"Overlook Boots","version":"1.0","type":"link"}
