One concern with sneakers being worn to work is the potential for injuries. Athletic shoes typically have a more rigid and durable sole than sneakers, which may provide less cushioning when worn on concrete or other hard surfaces. Additionally, sneakers do not offer as much support as traditional office attire when standing or walking for extended periods. If you are prone to experiencing backed-up veins in your feet, wearing high-heeled shoes can lead to discomfort and even further vein problems.
