Frequently Asked Questions

Do supportive slippers help plantar fasciitis?

Yes. Walking barefoot on hard floors is one of the worst things for the fascia. The Vionic Relax II has a genuine 17 mm built-in arch and eliminated our pain when walking on hard tile at home. Keep a pair by the bed so your first morning steps land on support.

Is the Vionic Relax II worth $60 for a slipper?

In our 6 weeks it held up over 120+ hours of wear with no arch breakdown, and the adjustable strap stops the foot sliding. It's indoor-only, so it's a second purchase on top of outdoor shoes, but for anyone with bad morning pain it was the highest-value item we tested.

Are flip-flops or slides OK for plantar fasciitis?

Only ones with a real contoured arch. Flat flip-flops offer nothing and force the toes to grip, which loads the fascia. The Vionic Relax II works because the arch is moulded in and the strap holds the foot in place: look for that, not a flat footbed.
