Very comfortable and a go to for my partner with his plantar fasciitis. He wears them everyday as they are very comfortable and supportive. He owns a few different styles and they really do help keep the pain away with their design and fit.
Emma –
Hello again! We received the flip flops today and you were right! Hubby loves them, we hope to buy more, we are planning a move out of Oz to Czech Republic so he wants some to pack, your new flip flops are winners! He finds them so comfortable. THANK YOU so much! SO very much appreciated.
John –
I bought these flip flops for my heel pain. I can’t believe how good they feel! Good arch and very soft cushioning. Well done guys!
Peter –
I’m 6 foot 3 and weigh over 260 lbs with flat feet and I wear flip flops daily around the house and sometimes when running errands around town. For those reasons I look for flip flops with as much arch support and cushion as possible. I also look for ones made of quality materials. I’ve only had these for 2 weeks now, but they are the most comfortable flip flops I’ve owned, and they have plenty of arch support (for a flip flop). Overall, I recommend these to anyone looking for a quality, comfortable flip flop!
Terry C –
Received these sandals yesterday and immediately tried them on, to my satisfaction they fit very good as I have wide feet. Very comfortable and good arch support and plenty of cushioning too. Terry
Alan F –
After receiving my flip flops and using them I was very pleased with the comfort and arch support. I have tried many orthotic sandals in the past these are the very best, can`t wait to buy my next ones. Alan
Richard L –
Replacing my ZORI flip flops which are about 2 years old and a little loose now, the KIRRA are very comfortable and a more snug fit. I have tried other orthotic flip flops, but these are the best.
Andrew –
Like all footlogics products I have tried so far, they appear to be of high quality and I think they will last a long time. They are very comfortable and I am very happy with my purchase.
John M –
Very happy with all the products I have purchased from Footlogics, including shoe inserts and these flip flops. Together they are giving me a lot of relief from my plantar faciitis. Coupled with some physiotherapy and various exercises, the condition is definitely improving. Also I appreciate the advice and support from Footlogics staff. Always quick to respond and help out!
Patrick D –
Received my pair today and I’m very happy with my purchase, great arch support and very comfortable fit, they are also light weight and don’t have the under toe ridge like other brands that my podiatrist warned me against. My only disappointment was you do not stock the ladies version for my wife to purchase.
Phil –
Received flip flops yesterday the arch area makes it so comfortable best keep up good work
Gary –
From the very beginning I found this product to be very comfortable and look forward to many hours of comfort and support for my feet.😀
Michael A –
Just received Kirra flip flops. Love them. From experience I have found how bad flat rubber flip flops are for your feet. Recovering from Arcilles injury. Thought I would be limited to shoes only but now looking forward to no sand in the shoes. Great support and comfort.
Frank –
The Zullaz “Kirra” Orthotic Men’s Flip Flops are the most comfortable footwear I have put on my feet in many years. I love them, Just fabulous. Thank You Footlogics.
John S –
Fantastic service. I ordered a pair of orthotics flip flops which were slightly larger than my usual size. When I provided feedback I was rung to see what the issue was. She offered to replace the flip flops with a smaller size and take back the original pair. The replacement flip flops arrived in two days. I highly recommend this company because of the great service and the quality of their products.
Tony Y –
Great product, very comfortable and supportive. Would recommend. Excellent service.
Andre G –
Very happy with the product, price, and service given before the purchase regarding sizing. Thank you
Barry S –
Hi my name is Barry and I have problems with my feet. I used to walk the beach every day with no shoes and now I have problems with flat feet which has cause archillies problems. So I purchaced a size 11 Zulus kirra orthopaedics. These are so comfy when I put them on they were made to fit. I would highly recommend them for anyone. These so good I am going to purchase another pair for later down the track. Thank you so much to the designer, they are fantastic.
Tony –
This is my second pair of Kirra flip flops. Bought the first pair because I hurt a foot and developed Plantar Fasciits. After a lifetime of preferring to walk around with bare feet I now prefer Kirra flip flops for the comfort
Stephen –
Hi, great product, good price, very comfortable and fast service, would highly recommend thank you.
Brian C –
Excellent product, I wear custom orthotics for Plantar Fasciitis and use these sandals for when lace up shoes with orthotic inserts are not convenient. Excellent product, well made and excellent fast delivery.
Peter K –

Coby F –
I brought these for my husband who suffers form foot pain and aching legs. My hubby lives in flip flops , and he can’t thank me enough for buying these!

I have recently bought my self a pear of these flip flops for the first time as I have seen suffering with sour feet for many years , oh the moment I put my feet in them I felt a relief, straight away thank you so much , I will never go back to the cheap ones again,.
Micheal –
Very comfortable. Most comfortable flip flops I have owned. Has relieved pain in my arch and bridge of foot.
James C –
So happy with my flip flops, the most comfortable flip flops I’ve ever owned. Didn’t know orthotic flip flops existed till I surfed the net to see what I could find. So glade I found these, it means I can start wearing flip flops again. I had stoped wearing flip flops because of leg pain as one foot was rolling inwards. I where orthotic shoe inserts that solved the issue with my shoes but didn’t know I could get orthotic flip flops. So happy, will definitely be buying these again.
Miriana P –
Bought for husband great and comfy!

Troy –
Very comfortable wont be buying cheap sandals again
Beren –
Gave it a month or so before posting this review to break these new flip flops in. So far so good! Great comfy feel, good arch support and perfect fit based on size charts on website. Great communication from Footlogic when my size wasn’t in stock, emailed me when they were and delivered really fast. Very hard to fault, it did take a few weeks to get used to the “zullaz” logo under the heel but no longer bothers me. Buy them…you won’t be disappointed.
Brian G –
Feel great so far still wearing them in worth the money
Sally –
Purchased for my husband. He said the most comfy flip flops he has ever worn. Very happy 😃
Herb. –
These flip flops are super comfortable as well as providing great support. The sizing was accurate (use the foot measuring guide on the Footlogics site. ) And the flip flops were sent and arrived quickly. All round 5 stars!
Ray –
These flip flops are very comfortable. I wear them both inside and out. Would like to see a version with an adjustable strap.
Gary –
I’m only sorry I didn’t buy these much earlier. Instant relief for foot pain and look good as well. Sizing was spot on and delivery very prompt. I’ll certainly be buying again.
Andrew –

John H –
My Zullaz ‘Kirra’ flip flops are very supportive while being extremely comfortable and stylish.
Victor –
I got a size 9 based on the size guide they have but when it arrived strap were a bit tight so I organised a replacement and they sent me a prepaid label to return the small size and got the replacement bigger size. Seemless process and good customer service. Will purchase more as I have done in the past as it really helps with my plantar fasciitiis.
Lo F –
Got a pair of these and they’re phenomenally comfortable. The relief to my plantar fascitis was immediate and they’re nice and cushy. Looking forward to wearing them when I go to the beach!
Debbie T –
These were for my dad who has got foot problems. I recommended them to him last year and bought him some. He has worn them so much as they make his feet feel so much better that he wanted another pair. Great for arch support.
Twinkle Toes –
So far the Zullaz flip flops seems to be well made and they become more comfortable each wear as my foot molds into it and my toes get use to the strap. I measured my foot as per the recommendation for sizing. I’m usually a 44 or 10 but went for size 11 and it fits well.
