Payments and Orders

  1. We accept debit or credit cards with the Visa, Master Card, American Express, or Discover logos issued in the United States. We do not accept checks or money orders. If you want to use a credit or debit card issued elsewhere, offers a personal shopper service that may be able to accept your payment method. Please visit's Personal Shopper help page for information.

  2. Your card is pre-authorized when you place an order to ensure that it can be charged when we ship your order. This pre-authorization or “hold” is a non-monetary transaction that checks that your account is valid and has sufficient funds. The duration of this hold is entirely up to your bank. Most banks will put a hold for these funds on your card. We don't charge your credit card until the order has shipped and is on its way to you.

  3. To verify your order was accepted, you will see a copy of your order receipt on the next page after you hit submit. You will also receive a copy of the receipt in your inbox. Many spam filters often catch these e-mails, so be sure to whitelist and check your spam filters for messages from us.

  4. If you are unable to process your credit card, please check that you have the correct card number, expiration date, and your 3 or 4-digit security number. Visa, Mastercard, and Discover cards use the very last 3-digit numbers that appear on the back of your card. If you are using an American Express card, the verification number is a 4-digit number that appears on the front of your card, above and either on the left or right of the card number. If your card does not have a verification number, try another card or enter the number 000.

  5. No, you cannot use multiple coupon codes. Only one coupon code per order can be applied. Coupon codes for discounted or free shipping apply only to orders delivered to a United States address. Voucher codes (including those from daily deal sites such as Groupon and Living Social) are considered coupon codes and cannot be redeemed in combination with additional coupons.
  6. Coupon codes can be applied at the very bottom while viewing the items in the shopping cart or on step 3, the Payment Information step.

  3. Please note it is important to consult a physician when making health decisions regarding your feet and whether to wear compression or diabetic socks.

    Both graduated compression and non-binding diabetic socks offer great health benefits to maintain healthy feet and legs, but both provide opposite benefits. Compression socks are effective in helping with venous disorders, such as tired, achy legs, varicose veins, edema, swelling, and deep vein thrombosis. They are also often used by travelers to help prevent blood clots or by athletes to decrease muscle fatigue. Compression socks are very tight around the ankles and lessen gradually up the leg to help force the venous blood back to the heart.

    On the other hand, diabetic socks are soft, nonbinding and are meant to provide no compression and allow circulation to flow regularly in the feet and ankles. Diabetic socks may help in the prevention of diabetic wounds and other foot problems from occurring. These socks are meant to help prevent irritations, offer comfort, and reduce pressure points.

  4. Dr. Scholl’s graduated compression socks come in many different compression ranges known as mmHg or millimeters of mercury. This unit of measurement measures the amount of pressure being exerted by the sock onto the foot. The mmHg measure originates from how many millimeters the mercury would rise when the air pressure changed. The higher the number, the more pressure exerted onto the foot and leg. Dr. Scholl’s Socks offers three different compression ranges: mild support at 10-15 mmHg, moderate support at 15-20 mmHg, and firm support at 20-30 mmHg.

  5. All of our sizes on our website are shoe-size ranges. Look for the sock size in the title of each product description page.
