Our innovative podiatrist-designed FMT Technology provides superior orthotic support, relief and stability which helps realign the feet back to their natural position.

Research supports FMT Technology's success in reducing over-pronation, which can help relieve associated common aches and pains, such as heel pain (plantar fasciitis), knee pain and lower back pain.

Fit & Care

  • Available in men's whole sizes 7-12
  • If you are a half size, we recommend ordering the nearest size down.

For the greatest comfort, we recommend wearing your new VIONIC footwear for just a few hours for the first few days to allow your feet to adjust to the new level of orthotic comfort and support.

Within one to two weeks you should find the product completely comfortable and supportive.

  • To preserve the appearance of your VIONIC shoes, we recommend that you clean the leather, if needed, using a dry, cotton cloth to wipe away dirt or dust.
  • Keep leather footwear away from direct heat to prevent the leather from drying out. If your shoes or sandals become wet, please allow them to dry naturally.
  • We recommend that you test any cleaning product by applying a small amount to a discrete area and allowing it to dry.
  • Do NOT use cleaners which contain acid or detergents, as they may damage and prematurely age the leather.

Having been introduced to Vionic Shoes a few months ago, they are now my number one choice for shoes ect.
The Alder Slipper is without doubt the best slipper I have ever purchased, they are not only stylish, they are very comfortable and good to walk around the house in, at the same time looking after my posture as the slipper includes the Vionic Biomechanical Footbed.
A very very happy and satisfied customer
