A loafer depends on its opening and instep fit
This listing offers the entry format but not how it adjusts, which materials form the upper or which width is offered. Check those details before assuming it will accommodate a high instep or a narrow heel. A loafer that needs toe gripping to stay on has not solved the convenience problem.
Compare with an identified slip-on rather than appearance alone
The other all-black men’s 11 slip-on entry has different wording and a different image; it is not established as this model in another size. Ask for the exact product identity and relevant workplace documentation. All-black styling may meet an appearance preference, but it says nothing about electrical properties, water entry or traction. Keep those questions separate from the decision to avoid laces.
