Testing status: the sandals named on this page have not yet been through our measurement protocol. This guide sets out the clinical criteria that decide whether a sandal helps or aggravates plantar fasciitis, and names the categories and models that meet them. No score and no seal appear here — those only follow once we have weighed, measured and worn the pair ourselves.
Why sandals are the hardest shoe category for plantar fasciitis
Most people with plantar fasciitis do well through winter and relapse in June. The shoe changes, and nothing else does.
A conventional trainer does four jobs for the plantar fascia at once: it supports the arch so the fascia is not the only structure holding it up, it cushions the heel strike, it resists twisting through the midfoot, and it stays on your foot without any effort from you. A flat sandal does none of them. Take the same foot that was comfortable in a supportive shoe, put it on a 4 mm flat slab of foam with a thong between the toes, and the tissue that was healing goes straight back to being the primary load-bearing structure of the arch.
The good news is that this is a solvable problem. Sandals that meet the criteria below exist in every category — recovery slides, walking sandals, dress sandals and house sandals. What matters is knowing what you are looking at.
The four features that decide it
1. A contoured arch, not a flat bed
The plantar fascia runs from the heel to the base of the toes and acts like a bowstring holding the arch up. Every time the arch flattens under load, the fascia takes the tension. A footbed moulded to the shape of the arch shares that load across a larger area, so the fascia is not doing all of it alone. Run your thumb along the inside edge of the footbed: you should feel it rise and stay in contact with your arch rather than leaving a gap.
2. A deep heel cup
You have a fat pad under your heel that is very good at absorbing impact, provided it stays under the heel. On a flat surface it spreads sideways with every step. A cupped heel keeps it where it is useful. This is the single most under-appreciated feature in a sandal, and it is why a firm contoured footbed often outperforms a soft flat one despite feeling less comfortable in the shop.
3. Torsional rigidity
Hold the sandal at the heel and the forefoot and try to wring it out like a towel. A sandal that twists easily lets your midfoot collapse and unwind through the whole step, and the fascia absorbs that. It should resist. It does not need to be a plank — a good sandal bends at the ball of the foot, where your foot bends, and resists everywhere else.
4. A strap that does the holding
This is the one people miss. In a backless flip-flop, the only thing keeping the sandal on your foot is your toes curling down on the forward swing. That is dozens of low-grade contractions of the intrinsic foot muscles and the fascia every hundred paces. An adjustable strap over the instep — better still, one round the heel — removes the job entirely. If you buy nothing else from this guide, buy a sandal with a real strap.
The 30-second test you can run in the shop
- Twist it. Heel in one hand, forefoot in the other, wring. Significant give means put it back.
- Bend it. It should fold at the ball of the foot, not in the middle of the arch. If it folds in half at the arch, it will not support one.
- Press the heel. Look for a defined cup you can feel with your thumb, not a flat pad.
- Look at the arch from the side. There should be a visible rise. Put your foot on it — the contour should touch your arch, not sit under thin air.
- Lift your foot. If the sandal only stays on because your toes are gripping, it is the wrong sandal.
Which category suits which situation
Contoured-footbed sandals — the everyday answer
Cork or moulded EVA footbeds with a pronounced arch and a deep heel cup. Birkenstock, Vionic and similar orthotic-footbed brands sit here. They usually satisfy criteria one, two and three well. The catch is that many models still leave the heel free, so check for a back strap version if you walk any distance. The other catch is that they are firm: people expecting softness find them punishing for the first week, and then most stop noticing.
Recovery slides — good for the end of the day, not for the day
OOFOS and the many imitators use a very soft, high-rebound foam with a mild arch contour. They are genuinely pleasant on an inflamed heel after a shift, and there is a real argument for having a pair by the door. But softness and torsional rigidity pull in opposite directions, and most of these twist easily. Treat them as a recovery tool for an hour in the evening, not as the sandal you walk three miles in.
Adjustable walking sandals — the best all-rounder
Chaco, Teva, Keen and the outdoor category generally. Firmer midsoles, real arch support on the better models, and — the important part — webbing straps you can tighten over the instep and round the heel. If you are going to be on your feet in a sandal, this is the category with the highest hit rate. Look for a model with a defined arch rather than the flattest one in the range.
Orthotic-friendly sandals — if you already have a device
A small number of sandals have a removable footbed, which means the custom orthotic or over-the-counter insole that already works for you can go straight in. This is the highest-percentage option if you own a device you trust. Our insole comparisons cover which devices transfer well between shoes.
House sandals — the category everyone forgets
Most plantar fasciitis flares are built at home, barefoot on hard floors, in the twenty minutes after getting out of bed. If your morning pain is the worst part of your day, a supportive sandal or clog kept beside the bed will do more for you than any outdoor pair. Put it on before the first step.
The sandals worth shortlisting, and who should skip each
A sandal has to do the arch’s job without the upper’s help, which is why so few of them manage it. These are the ones that do. Nothing here has been under our own caliper, so nothing carries a score or the seal.
Birkenstock Arizona — the contoured cork footbed
The reference sandal for this problem, and it earns it: a deep heel cup that cradles the fat pad, a defined arch, and a toe bar that stops the toes gripping to keep the sandal on. The cork moulds slightly to your foot over a few weeks, so the fit improves rather than degrades. Two adjustable straps mean the fit can be set for a foot that swells through the day.
Skip it if: you are in an active flare and need cushioning right now — the footbed is firm, and the soft-footbed version is the one to buy if the heel is currently sore. Also skip it if you have neuropathy; an open sandal with a firm footbed on a foot that cannot feel a rub is how small problems become wounds.
Vionic adjustable sandals — the built-in orthotic
Vionic’s whole premise is a moulded footbed with a real heel cup built into the sandal rather than sold separately, which is precisely what plantar fasciitis needs from a sandal. The adjustable versions let you position straps away from a pressure point, and the range includes closed-back styles that hold the heel far better than a slide.
Skip it if: you already wear prescribed custom orthotics — a moulded footbed and your own device will fight each other, and you want a flat-bedded sandal with a strap that will take the orthotic instead.
Oofos OOahh — the recovery slide for a sore heel
Different job from the two above. There is little arch structure here; what there is instead is a very soft, thick, rockered foam bed that absorbs impact and lets the foot roll rather than bend. For the evening after a long day, or the first few weeks of a flare when firm support is intolerable, this is the sandal that actually gets worn. It also protects the heel during the barefoot indoor hours that undo most of the good work.
Skip it if: you are looking for arch support — it does not provide meaningful structure, and it should not be your only sandal if your fascia needs holding rather than cushioning. It is also a backless slide, so the toes work to keep it on over any distance.
Teva or Chaco with a strapped heel — for walking distance
If a sandal has to cover real ground, the heel has to be strapped — a backless sandal makes the toes grip to hold it on, which fatigues exactly the muscles supporting the arch. Chaco in particular builds a genuinely contoured footbed with a defined arch under a strap system that can be tuned around the foot, which puts it closer to a walking shoe than a sandal in how it behaves.
Skip it if: the arch does not match yours. The support is pronounced and fixed, so an arch that sits in the wrong place is a pressure point you cannot adjust away — this is a sandal to try on rather than order blind.
What to stop wearing
Flat rubber flip-flops are the single worst footwear choice available to someone with plantar fasciitis: no arch, no heel cup, no heel retention, and a toe post that makes the foot claw with every step. A summer spent in them is a common reason heel pain arrives in the first place. If you want the convenience, buy a contoured sandal with a strap and keep the flip-flops for the poolside.
Skip it if
- It is a flat flip-flop. No arch, no heel cup, no strap. There is no version of this that helps a plantar fascia, and the toe-gripping actively works against you.
- Your heel pain is sharp, localised and worse on the first step but has lasted more than six weeks. Footwear is part of the answer, not all of it. That pattern deserves an in-person assessment before you spend more money on sandals.
- You are buying a soft recovery slide as your only summer shoe. Excellent for an hour of recovery, poor for a day of walking.
- You have diabetes with any loss of sensation. Open footwear plus reduced protective sensation is how small injuries become serious ones. Take this decision with your clinician, not from a buying guide.
- The arch contour does not touch your arch. A moulded footbed built for someone else’s foot is a flat sandal with extra marketing.
How to change over without a flare
The mistake is going from a supportive trainer to a sandal on the first warm day and wearing it for eight hours. A firm contoured footbed asks your foot to sit in a new position, and the tissue needs time. Two hours on day one, add an hour a day, and stop for a day if the morning pain gets worse rather than better. If you have gone a fortnight and the mornings are still worse than they were, the sandal is wrong for your foot — that is information, not failure.
For the rest of the year, the same four criteria apply to closed shoes. Our main plantar fasciitis guide covers work, running, home and dress options, and the slipper guide handles the indoor half of the problem.
