Measure your foot length in centimetres for the most reliable fit. The sizes you can order today are the ones listed in the size dropdown on the product page.
How To Measure Your Foot Length
- Place a sheet of paper flat against a wall.
- Stand on it with your heel touching the wall and your weight on that foot.
- Hold a pencil upright at the tip of your longest toe and mark the paper.
- Measure from the wall edge of the paper to your mark. That is your foot length.
- Add 3 to 5 mm so your toes have room.
- Compare the result with the chart above.
Measure both feet and use the longer one. Feet also swell over a long day, so measure in the afternoon or evening rather than first thing.

Comfort You Stop Noticing
The best shoes are the ones you forget you are wearing by mid-morning. Here is what that takes.
Slip On, Head Out
Step in and go. A stretch-knit collar and firm heel mean no laces to fight, nothing to fasten when your back already aches, and no break-in period first.
All-Day Cushioning
A supportive insole and a shock-absorbing midsole, so hour twelve feels a lot closer to hour one.
Featherlight Build
Breathable knit and a light sole. Your legs are not hauling extra weight around all day.
Why Comfort 2.0 Works
On In Seconds, No Bending Down
The stretch-knit collar and cushioned heel let you step straight in. No laces to fight, nothing to fasten when your back already aches, and no break-in period first.
Room Where Your Toes Need It
Your forefoot is the widest part of your foot, yet most trainers taper exactly there. Ours doesn't. Your toes spread naturally, which is what stops that ache across the ball of your foot by mid-afternoon.
Hard Floors Stop Travelling Up Your Legs
Triple-layer cushioning takes the impact at the heel so your knees and lower back don't have to. You notice it most on tile and concrete.
Light Enough To Forget You're Wearing Them
A breathable knit upper keeps feet cool and dry through a long day, and the sole is light enough that your legs aren't working overtime by the evening.
Still Supportive At Month Six
A structured heel cup and real arch support that hold their shape shift after shift, not cushioning that flattens out three weeks in.
One Pair That Covers The Whole Day
Long shifts, the school run, errands, an evening walk. One pair you can leave by the door and stop thinking about.
FOUNDATION FIRST
Strength Starts
With Your Feet
Your feet carry every step you take. Give them room, cushioning and a stable base, and the rest of you stops paying for it.
- A stable base keeps you balanced on your feet
- A flexible sole lets your foot move the way it's meant to
- Comfort that makes you want to walk more, not less
Designed with foot health in mind
Engineered for All-Day Pain-Free Comfort
Wide Toe Box
Your forefoot is the widest part of your foot. This is the rare shoe that is widest there too.
Natural Alignment
A supportive footbed keeps ankles, knees and hips stacked the way they are meant to be.
Cushioned Soles
A shock-absorbing midsole soaks up hard floors before the impact reaches your joints.
Stable Base
A grounded, grippy outsole so you feel planted on tile, concrete or a wet floor.
