While not leather, because of the all black color, they essentially go unnoticed and in the end, I appreciate the breathability and lighter weight.
Sam kindly contacted Hoka to see if I could review a pair of leather Bondis, which unfortunately were not available, but they were able to provide an all black pair of Bondi 5. I'll not say the name, but let's just say the company is massive, known for utilizing the color brown and requires us to wear a black or brown leather boot/shoe. I am between jobs/careers and in the interim while I look for something more long term, I took a seasonal delivery driver position with a major Worldwide delivery service.
