Justin Men's Derrickman 12" Waterproof Wide Square Comp Toe Work Boot (Caramel Croc Print)

Justin Men’s

Boot sizes

Justin label that last column only “CM”. They don’t say whether it is your foot or the boot, and they publish no foot-length-in-inches chart at all — so use it as a conversion reference, not as something to measure your foot against. There is no men’s size below 6 or above 16 on their chart.

Widths

Justin publish no foot-width measurements to go with these letters. Their advice is simply to “get professionally measured at your local retailer” — which is us, so come in. You will also see D shown as M and EE shown as W on some Justin listings; those are the same widths under different labels.

Getting the fit right

• The pop. Justin: “you should hear a ‘pop’ as your foot slides into place.” No pop usually means the boot is too big.
• Heel slip is meant to be there. “A slight heel slip (about ¼ to ½ inch) is perfectly normal.” It settles as the sole flexes.
• Instep. “The top of your foot (instep) should feel snug, but not tight.” That is what holds the boot on.
• Ball of the foot. “The ball of your foot should align with the widest part of the boot.”
• Toes. “About a thumb’s width of space between your longest toe and the tip.”
• Measure late in the day — Justin’s own tip — “when they’re at their largest.”

Shaft heights

Justin sort their own boots into three heights: short (9″), mid (10–12″) and tall (13″ and up). Most of what we carry is mid. The exact shaft height is in the product title or on the product page.

All of the above is from justinboots.com. A note on what Justin do not publish: no separate fit or sizing guidance for their work boots — Original Work, steel toe, composite toe and nano comp toe all run off this same chart, and Justin say nothing about safety toes fitting differently. J-Flex is a cushioned insole and insole board, not a different last, and Justin publish no fit difference between the Stampede, Bent Rail and AQHA lines either. One older Justin fit article says to expect about an inch of heel slip, which contradicts the quarter-to-half inch on two of their newer pages; we’ve gone with the quarter-to-half.
