Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.
