Socks make a difference and I love these cushioned socks from thorlo, they're simply the best!  It's the padding in the right places that make these socks so special. I thought the price was crazy so I only bought one pair initially, but eventually I broke down and bought a weeks worth. Right now they are having their semi-annual sale where if you buy 3 you get 1 free. I also use their everyday socks for hiking. You can try their socks for free + the cost of shipping with this offer.

We created Thorlos clinically-tested padded running socks (CTPS) over 30 years ago—in fact, they were our very first activity-specific padded socks, designed specifically for runners, based on their feedback about what sock characteristics could help them most. 

The AMX Fitness sock is for those who who enjoy getting in shape and staying fit. In a Zumba or other conditioning class, at home, or in the gym. Cushioned instep and arch plus spandex for a better fit, more support and less pressure on the feet for more comfort while exercising. Constructed with THOR•LON® fibers for superior softness, resilience, durability, and moisture-wicking for drier, better feeling feet. Unique padding specifically engineered for fitness activities, clinically shown to reduce blisters, pain, pressures, and moisture.
