Size 18 Football Boots: What We Found in the UK
Quick answer: no shop we checked had a football boot in stock in UK 18 on 30 October 2026. The one listing we saw was at Pro:Direct, where the adidas Kaiser 5 Team and Kaiser 5 Goal list 18, but both were sold out. The football boots we found in stock ended at 16, on the Sondico Strike. We did not check Amazon UK for this size.

- Football boots in stock at 18None found
- Listed but sold outadidas Kaiser 5 Team and Goal (Pro:Direct)
- US size19 (Nike chart, Walktall)
- Foot length for UK 1813 11/16 in, about 348 mm (Nike chart)
Eighteen is two sizes past the end of every football boot range we found with stock. Even the shops that go furthest, Sports Direct and Lovell Soccer, stop at 16, and only on one model; Pro:Direct’s listing at 18 was sold out. So this page sets out the two things that are useful at 18: where each range stops, and how big a UK 18 is on the charts we found.
We checked each shop’s own website on 30 October 2026, reading football boot filters and, at Pro:Direct, Lovell and Walktall, the shops’ own store data. We did not check prices. We did not check Amazon UK’s listings.

Sizing at 18
Nike’s men’s shoe chart gives 13 11/16 inches, about 348 mm, for a UK 18, with EU 53.5 and US 19, although Nike’s own size filter stops at 17. The chart is in inches; the mm figure is our conversion. Walktall’s conversion table gives EU 53 and US 19, with no foot length. Measure the length and the widest part of both feet, in the evening, and give a shop both numbers if you ask about a boot.

Most items can be returned within 30 days, but only items marked Free Returns are free to send back; otherwise the cost may be deducted. Search size 18 football boots on Amazon UK.
