I switched to Monfoot almost 2 years ago, and since that moment on I have not regretted it. I did one time have a manufacturer error that I noted and reached out to the customer service dept and they quickly took care of me and sent me a replacement pack! The quality overall is just phenomenal and they are comfortable all around. I do hope maybe in the future they would have crew socks in Large and not just in medium or small but nonetheless, overall phenomenal quality and very comfortable all around and the customer service department is outstanding and courteous. Highly recommended to anyone looking to make a switch!
