Choosing sports shoes and sports sunglasses: practical tips for comfort, grip and protection

If you’re looking for sports shoes and sports sunglasses, you’ll usually want to make your choice quickly. Yet many models look alike. A low price can be tempting, but the wrong fit, insufficient grip or lenses that aren’t suited to how you’ll use them can soon make a purchase impractical. Use these checks to avoid the most common buying mistakes.

Three common pitfalls when buying

1. Wearing the same shoes on every surface

Road running shoes aren’t automatically suitable for woodland paths, sports halls or artificial grass. The sole determines how much grip you have and how stable you feel as you move. If you wear ordinary trainers for intensive training, you may also notice a lack of cushioning or support sooner.

So check the stated use:

  • Running shoes are generally designed for hard surfaces.
  • Artificial grass football boots have a turf sole with multiple short rubber studs.
  • Walking shoes often have a deeper tread for uneven paths.
  • Casual trainers are mainly intended for everyday wear and light activities.

2. Choosing your size based only on the number

An EU size isn’t exactly the same across every brand. The shape of the last, the width around the toes and the thickness of your sports socks can all affect the fit. Measure your feet at the end of the day, when they’re often slightly larger.

When trying on shoes, check for:

  • about a thumb’s width of space in front of your longest toe;
  • no pressure across the top or sides of your foot;
  • a heel that doesn’t slip up as you walk;
  • enough room when you wear thicker socks.

For the Warrior models in this selection, foot length is listed for each EU size. That’s more helpful than relying solely on sizes 39, 40 or 42.

3. Choosing sunglasses based on how dark the lenses are

Dark lenses don’t automatically mean that a pair of sunglasses offers sufficient protection. Check the product specifications and look for UV400. This label indicates protection against UV radiation up to 400 nanometres. Also check whether the sunglasses are suitable for cycling, running or everyday wear.

Polarised lenses can reduce distracting glare from water, wet roads and car windows. However, that doesn’t automatically make a pair suitable for every situation. In low light, dark lenses can actually restrict your vision. According to the product specifications, photochromic lenses adjust their tint to the amount of UV light, but they may not darken as much in a car because the windscreen blocks UV radiation.

Key specifications to compare

Sole, grip and surface

For road running, cushioning, a smooth roll-through and a rubber outsole are all worth considering. According to the product description, the Salomon Spectur models feature an Energy Surge foam sole, R.Camber geometry and a rubber outsole. These features are designed to provide a smooth heel-to-toe transition and grip on hard surfaces.

For artificial grass, the type of sole is what matters most. The Joma FS Reactive 2402 TF has a rubber sole with multiple turf studs. The product description specifies that this version is for artificial grass pitches. Don’t use this type as a general substitute for running shoes.

Cushioning and stability

A soft midsole can feel comfortable on longer walks or runs, but the feel varies from person to person. So look at the materials and construction rather than relying only on terms such as “comfortable”. A dual-density construction, such as the Foam Reactive and Phylon sole in the Joma, gives you an idea of how the sole is built.

For comfortable sports shoes, the upper and fastening are important too. Mesh can help with ventilation, while synthetic overlays or a secure lacing system can provide a more supportive fit.

Lens type, protection and fit

For cycling glasses and outdoor activities, these features are useful to consider:

  • UV400: check that this is stated explicitly in the product specifications.
  • Polarisation: can reduce glare, especially outdoors on bright days.
  • Photochromic lenses: according to the product description, the tint changes depending on UV exposure.
  • Impact resistance: impact-resistant lenses aren’t unbreakable and aren’t a substitute for safety glasses when working.
  • Nose support and non-slip material: important when you’re moving or sweating.

Remember to look after your glasses too. Clean the lenses with a microfibre cloth and keep them in a hard or protective case. Scratches can affect your vision.

Frequently asked questions about sports shoes and sports sunglasses

Are polarised sports sunglasses suitable for cycling?

They can be, especially in bright light and when there’s glare from wet roads. Check the lens category, fit and ventilation too. For cycling, glasses with a secure nose bridge and a close fit around the eyes are often more practical than standard sunglasses.

How long do sports shoes last?

How long they last depends on your mileage, body weight, the surface, care and storage. Don’t just look for wear on the outsole. A compressed midsole, seams coming apart or a less supportive heel counter are also signs that it’s time for a new pair. Alternating between two pairs can help reduce wear on each pair.

Are UV400 sunglasses suitable for low light?

UV400 tells you about UV protection, not how much visible light the lens lets through. Dark lenses can be impractical at dusk or in overcast weather. If conditions vary, consider a photochromic version and check the stated lens category.
