The SI-18 Rival takes inspiration from some of our heritage models from the 1980s and 90s. By taking the upper from the Si-18 Rannell training shoe and putting it on a cup sole bottom inspired by the iconic Si-18 Premier tennis shoe, we have made a sneaker that is fresh and new yet still authentic to our heritage tennis roots.

Size chart

Every brand we carry cuts a little differently, so use the brand-specific charts below alongside the notes on each product page. If you're ever between two sizes, or comparing brands you haven't worn before, our team is happy to help before you order.

Footwear

Footwear sizing differs by brand, so check the chart for your brand below. As a general rule, South African (SA) shoe sizes match UK sizes.

If your foot measurement falls between two sizes, K-Swiss recommends sizing up. Measure both feet and use the larger one. If buying a men's K-Swiss style as a woman, size down 1.5 sizes from your usual women's US size.

Novesta, Chapman & Moore & other footwear brands

Novesta shoes fit true to size — choose your usual size to start. Because sizing can vary between individual Novesta models (e.g. Star Master vs. Itoh), see our detailed Novesta measuring guide if you want to double-check a specific style.

For other footwear labels we don't yet have a brand-verified chart for, SA and UK sizes match as a general starting point, and you can use the table below to estimate EU/US equivalents and foot length.

SA / UK	EU	US	Foot length (cm)
6	39	7	24.5
7	40.5	8	25.4
8	42	9	26.7
9	43	10	27.9
10	44.5	11	28.9
11	46	12	30.2

General reference only, not brand-verified — if you're unsure, message us the exact style and we'll check with the brand where we can.

Clothing

Sizing below is brand-specific where we have it. For brands not listed, treat sizes as approximate and check the product page for any fit notes.

"Chest width" is the garment measured flat from side to side, not the full circumference — double it for a rough circumference comparison against a tape-measure chest reading.

Cuba Libre, Chapman & Moore & other clothing brands

We don't yet have a brand-verified chart for these labels. Shirts here tend to run true to size to slightly slim through the chest — if you prefer more room, consider sizing up. As a rough guide:

Size	Chest (cm)	Chest (in)	Waist (cm)	Waist (in)
XS	86–89	34–35	71–74	28–29
S	90–94	36–37	75–79	30–31
M	95–99	38–39	80–84	32–33
L	100–104	40–41	85–89	34–35
XL	105–109	42–43	90–94	36–37
XXL	110–114	44–45	95–99	38–39

Hats & Caps

Most of our trucker caps and snapbacks (Goorin Bros, Cuba Libre) are adjustable and listed as one size. For fitted and structured styles, check the chart for your style below.

Fitted & structured styles

We don't yet have a brand-verified chart for most of these styles, so treat the table below as a starting point.

Size	Head circumference (cm)	Head circumference (in)
S/M	54–57	21.25–22.5
L/XL	58–61	22.75–24

How to Measure

Feet

Stand on a piece of paper with your heel against a wall. Mark the tip of your longest toe, then measure from the wall to the mark in centimetres. Measure both feet in the evening (feet swell slightly through the day) and use the larger measurement. If you're between sizes, it's usually safer to size up.

Chest & Waist

Chest: wrap a tape measure under your arms, around the fullest part of your chest, keeping it level and snug but not tight. Waist: measure around your natural waistline, just above the belly button.

Head

Wrap a tape measure around your head about 1.5cm above your eyebrows and ears, at the largest point. If you don't have a tape measure, a piece of string measured against a ruler works just as well.

Between two sizes? For footwear, size up for boots and structured leather, and follow the brand chart above for sneakers. For clothing, size up if you prefer a more relaxed fit.

Still not sure? Contact us with the product name and we'll help you find the right fit.
