For about four weeks of the year, white trainers make sense. Five, if we're lucky.
The clouds disperse, pavements shimmer in the heat and puddles become a dim and distant memory of winter. It's in these hallowed weeks that white footwear isn't just permissible - it's downright essential.
We've perused the summer's latest trainer releases to bring you the best gleaming white looks, box fresh and ready for lawn season.
And don't you even think about wearing them for a cheeky kick around, okay?
Nikecourt Air Trainer 1 x Fragment
Nike's tribute to the tennis season, this collaboration with the design bods at Fragment sees the padded Nikecourt shoe decked out in a range of new colourways - including this immaculate white number. Don't expect to see Murray sporting them on Centre Court any time soon though. He's sponsored by Adidas.
ASICS GEL-Kayano EVO Trainer
The Gel-Kayano is one of the most varied designs of ASICS, with over 20 different iterations hitting the streets since its launch in 1993. This all-white belies its pure appearance, with a tough outer shell of the stag beetle material and skeletal overlay.
Vans Old Skool Leather
Calling on an older style when it was introduced back in 1977, the Old Skool is still a traditional gem all these years on. A heavier leather than most of the shoes in our collection, you can pair these with shorts or a slim trouser.
Reebok INSTAPUMP FURY ROAD
We've searched every inch of this trainer for references to the latest instalment of Mad Max, but there's not a scrap of Hardy in sight. In its place is an abundance of blown rubber, cushioning and foam to deliver the comfortable ride Reebok's pump range is famed for.
Nike Air Huarache Triple White
A classic whatever the weather, the "triple white" Huarache is a true chunk of a training shoe.
Adidas Originals Racer Lite
With an aesthetic similar to something out of Tron, only the bold are going to like the look of the Racer Lite - but for those who fall for its curved charms, it's a breathable, lightweight fit that'll keep cool from the ankle down all summer.
Puma Court Star Emboss WT
A trim, minimalist stalwart, the Puma Court Star is better suited to block colourings. A traditional tennis shoe, think of this of the 'Wimbledon' model.
Greats ROYALE HIGH LEATHER HIGH-TOP SNEAKERS
An offering from the luxury end of the trainre scale, this Greats high-top is awash with Italian leather, with subtle stitching on the sectioned side panels. Only a brave man will take these on holiday.
adidas Originals Stan Smith 'Tournament Edition 3.0'
New Balance CRT300
New Balance have become something of the casual shoe kings of late, winning over fans disgruntled by a lack of imagination from Nike and Adidas. Their court shoe is a low profile ace, blending clean leather with mesh panelling and a splash of blue on the heel cover.
NPC UK II x Oi Polloi
Converse Chuck Tailor All Star Hi
A true legend of footwear, if Ridley Scott's Alien is on the money, deep space travellers will still be sporting this canvas shoe centuries into the future. They probably won't, but you try writing a sales pitch for a shoe that's been "cool" since your parents were kids.
AMI LEATHER AND SUEDE SNEAKERS
The French fashion house keeps things simple with this leather and suede look: metallic eyelets match an otherwise monochrome palette of crocodile-effect white leather, grey and black suedes.
