The wedge construction
Carhartt lists Storm Defender waterproof protection, a dual-density rubber outsole and a polyurethane cushion insole for the six-inch steel-toe moc wedge. The outsole is designed for broad ground contact rather than a sharply separated heel. That is a meaningful difference from a lugged Wellington when evaluating where you stand and walk.
A wedge shape alone does not prove better grip on your floor. Wet smooth concrete, loose soil and ladder rungs present different demands. If your job requires a defined heel, check the site rule before choosing this outsole just for its continuous shape.
The medium-width soft-tan selection
This record is 9.5 medium in soft-tan leather. The 10.5 wide listing is another size and width in the same model family, not a different comfort technology. Start with the correct length and compare width where available; going longer to escape side pressure can move the foot away from the intended bend point.
The moc seam gives the upper its characteristic appearance, but it does not tell you how roomy the steel toe is inside. Fit it with work socks and check toe clearance while stepping down as well as standing.
Wet use without unrealistic promises
The manufacturer identifies this family as waterproof. Water can still enter through the collar, and perspiration can accumulate inside during active work. Let the boot dry between wears according to care instructions, and inspect the upper and sole joint when leaks or damage appear. No personal wear-test or lifetime durability claim is implied by this description.
