The Western Buckle Straps Chunky Heeled Side Zip Boots are shown in Brown and Black with a rounded toe, side hardware and a zip closure. The current selectors offer sizes 35–40. A shopper can find a foot-length chart and a listed 16 cm boot-tube height, but there is no shaft-opening circumference. That missing number matters if you want the upper edge to sit comfortably around your ankle or over a tucked trouser.

Check the opening before choosing a trouser

Put on socks and the trousers you expect to wear with ankle boots. At the height where the top of a similar boot sits, wrap a soft tape around your leg without pulling it tight. Repeat with the trouser leg tucked in if that is your intended look. Measure an ankle boot you own at its upper edge while it is zipped, then compare how much space it leaves when you walk and sit. This gives you a personal reference; the listing does not state the MAXCT pair’s opening circumference or the exact point used for its 16 cm tube-height figure. Ask for the zipped opening measurement if the difference between over-trouser and under-trouser wear is important.

The gallery shows buckle straps on the outside and a chunky-looking sole, but it does not establish that moving a buckle changes the shaft width. Do not count on the straps to solve a narrow opening without that detail being confirmed. The side zip is listed as the closure; check the photographs for its position, then ask for a close view of the opening and zip if access is a concern.

Use the foot-length row separately

The chart pairs size 35 with 22.34 cm foot length, 36 with 23 cm, 37 with 23.66 cm, 38 with 24.32 cm, 39 with 24.98 cm and 40 with 25.64 cm. These are foot-length recommendations in the listing, not inside-sole lengths or a guarantee of toe room. Measure both feet from heel to longest toe while standing and use the longer value as your comparison. If your foot falls between rows, ask about inside length and toe-box width before selecting solely from a US or UK conversion. Our Chelsea boot fit guide gives another example of why foot length and boot width are separate decisions; its size numbers belong to a different product and must not be substituted here.

Keep the heel description precise

The product specification gives a 3 cm heel height but also labels the heel type “flat.” The gallery shows a raised, block-like heel. These labels do not settle the exact rise under a particular size, so confirm the measurement if heel height is a deciding factor. The source lists a PU upper and EVA outsole; it does not supply an independently tested grip rating, waterproof rating or wear-life claim. A useful purchase check is therefore three separate questions: does the foot-length row suit your foot, will the zipped opening fit your ankle or trouser, and is the heel height the one you expect?
