Very quality socks. They rival the big names (Feetures, Balega, etc.) of which I also have pairs. They are definitely worth a try especially because the prices are often discounted. Plus, customer service is SUPERB. I bought 2 pairs of thinner socks from SwiftWick and I contacted the customer service informing them that after running in one of them, I would have preferred to try the thicker options (Vibe and Maxus). The next thing I knew, I had an order confirmation in my inbox for 2 new pairs of socks (the Vibe and the Maxus) free of charge! WOW! The company really wants you to be happy with your purchase!
