02Product details

All about this gift.

You are giving a prepaid subscription with one pair of branded socks per month. You choose 3, 6 or 12 months, and the recipient chooses their shoe size and starting month. The gift subscription ends automatically at the end of the chosen term and incurs no further charges.

What is included

  • A voucher for 3, 6 or 12 monthly deliveries
  • Printable voucher ready straight away, or a ready-to-give gift box delivered free of charge
  • The shoe size and starting month are chosen by the recipient
  • Original items, bought directly from the brands
  • Free delivery in Switzerland and Liechtenstein, with no minimum order
  • Ends automatically, with no renewal and no further charges
How does this gift work?

You choose the term, then place a single order. The voucher is ready straight away: the link to print it arrives with your order confirmation. If you would rather have something to hand over, it is sent in a rigid gift box with a personal card, delivered free of charge within 2 to 3 working days. The recipient activates it on undy.ch, enters their shoe size and chooses their starting month.

Do you need to know the recipient's shoe size?

No. The recipient enters their shoe size when activating the gift, from 39 to 46. They also decide when the subscription starts, choosing from three possible months. Activations received by the 12th of the month can still be sent out that same month.

Why is the brand a surprise?

Every delivery is a chance to discover a new pair of branded socks. The size is chosen, and we select the model: the brand, colour and pattern are revealed when the box is opened. It is a way to vary styles and discover socks one might not have chosen oneself.

Which brands can arrive?

Tommy Hilfiger, Calvin Klein, HUGO, BOSS, Lacoste, Gant, Nike, Adidas, Puma, Reebok, New Balance and other brands from our range.
