Purchased the briefs that were a bit long and a size too big for me - but very comfy. Contacted customer services and the response was efficient and excellent. Within a few minutes of emailing I have an exchange sorted for the shorter ones and a smaller size. Top notch.

Fact one: takes a very long time to receive them, Fact 2: international sizes : XXL is in fact a medium size not a XXL size as in Australia, as example: China Made international Sizes: didn't return and pay more money, gave them to my 14 year old.

Brilliant website and will definitely buy more step ones and recommend to friends and family as the step ones are so comfortable and great value for money and very quick postage too

They are noting more than basic underwear. Make something dearer & run a good advertising campaign & they will come. Not even worth sending back as the post cost makes that not worth worrying about. Don't get sucked into the hype. You buying their TV ads & that's a fact

At first I was impressed with how they felt, that’s where it ended. The legs rolled up throughout the day, the waist band kept folding over. And worst of all, kept getting wedgies all day. Thank god I only purchased one to start with. I have now reverted back to my old ones.

Therefore I can not recommend these at all

Great item that feels amazing. So simple to order & use ‘First pair’ guarantee. Great customer service staff, thanks. Looks fantastic on & will be back for more. Dads day is nearly here!!

I bought 2 pairs n found them to keep slipping down waist so ordered smaller pair n hope same don’t happen? Apart from that found them to b comfortable so fingers crossed

I find that they do ride up i brought them thinking they wouldn't. For that and only that im not satisfied. Everything else gets a tick though, not sure if i have thick enough legs which i think i do.

I’m a big fan of the product. Thank you to StepOne replacing my first pair, exchanging from ‘medium’ to ‘large’.

I have my waist measurements correct. I have 5 pairs now at “large”, but the waistband on this underwear is extremely tight, continually folds & is uncomfortable. The waistband is like a resistance band at the gym - it’s ridiculously constrictive, not anything remotely comfortable around the waist.

They do ride up, but not a great deal. That’s to be expected, I guess. The material and colours/ appearance is terrific.

I am disappointed as I’ve tried two size options now, have 5 pairs but still not satisfied. I’d love to keep buying these, but I can’t because of the sizing complexities & waistband issues.

I ordered 2XL but when I put them on they were clearly too big.
Under the "1st pair satisfaction" guarantee system the company changed them with absolutely NO FUSS!
The new ones are a perfect fit, the Gentleman's Vegetables drop straight into the pouch with no fiddling around............ didn't ride up all day.
Ordering more today.

Ordered an initial pair (trunk shorter) size was posted as large,when arrived I could hardly get them on, was small/medium at best,e mailed to complain heard back nothing,good at one liners poor customer service.

So comfortable. Thrown all my others out. Could do with more colours. No more riding up and feeling uncomfortable. Wish i bought them sooner. Delivery was very quick considering the current situation

My daughter Anna P got me onto StepOne after she met an employee of StepOne on a flight. I have to say they are the most comfortable undies I have ever had. You actually feel naked under them. They feel food and look pretty good too. I got seven pair and would never buy anything else.

Comfort plus ...I do a lot of walking, hiking and running and they are comfortable and supportable. Keepa me dry and half the time you don’t even think your wearing any.

I bought 1 pair to try it out and i couldn't believe how good they feel, i own 5more now... even the customer service team is very helpful and there to answer my concern

Overall best

The site and ordering was simple. The size guide was inaccurate for me and I should have ordered at least one size larger. I can see their potential but being undersize left me less than impressed. The fabric is very soft and you hardly know you’re wearing them.

Super easy to find and choose products. Super satisfied with the product itself and the service i’ve received whilst exchanging sizes has been really good! Highly recommend the product and highly rate the service!

I bought 4 x short trunks in medium as my husband is a size 87. He sweats ALOT in our line of work so thought these would be good for him. Alas, these ones do ride up, so I was straight on to customer service to see if something could be done. I emailed them around 8pm at night, thinking I won’t hear from someone till the next day.....well I was shocked when Matt replied literally within 10mins saying he can post out a small size for my husband to try! Just want to do a shout out to Matt for exceptional customer service, thank you so much!
