What size am I?
- Stand vertically on a piece of paper and trace your feet. Then measure the maximum length in cm and determine your UK size
- Please do not add anything to this. Yes, your foot needs some space because the foot moves in the shoe as it rolls. This has already been taken into account in the table when converting.
- If you have wide feet, you don't need to add anything, as almost all Jim Green shoes are already wide. Wide width EE (almost all Jim Green models). Normal width D (e.g. Shoellie, Baobab, Numzaan) .
- Please call us if you have any doubts. Shop with peace of mind as you can exchange your size at any time.

What soles are there?
What soles are there?
Here is an explanation of all Jim Green soles. You can find out which sole this model comes with in the item description.
JG Sole – This sole is our lugged variant and was developed for grip. It is made of real rubber and feels firm to provide stability underfoot. The JG Natural Rubber option is softer, but still offers the same properties. Best suited for loose gravel surfaces, rocky terrain, uneven terrain, and challenging landscapes.
OR Sole – This sole is designed for a combination of grip, comfort, and speed. It is made of real rubber and offers a softer feel for greater walking comfort. Best suited for sandy areas, long days on your feet, fast hikes, urban areas. A great lightweight hiker.
BR Sole – This sole is our all-rounder option and was developed for durability in urban and outdoor environments. It is made of real natural rubber and has a firm grip to provide stability underfoot. Best suited for days between office and outdoor activities.
FA Sole – This sole is our lightweight comfort variant and was developed for comfort and a slimmer look. It is made of a real, soft rubber compound and feels softer and more comfortable. Best suited for relaxed days in the city or light hikes and camping trips.
KH Sole – This sole is designed not to pick up mud and dirt during your daily activities, hence its "flat" design. It is made of real rubber and feels firm to provide stability underfoot. Best suited for muddy ground or sandy areas.
ANV Sole - The Anvil sole is designed to mimic the feel of barefoot walking on any terrain, while providing extra grip and protection. A sole without any reinforcement or stiffening.
TW Sole - This sole is our Tyre Wedge option and is designed for grip and comfort. It is a real rubber sole with a softer rubber compound to provide the best all-around performance.

This section explains the different lasts. You can find out which last this model has in the item description.
- JG last = EEE width
Jim Green last. Very wide fit, normal toe box height. Toe cap reinforced with thermoplastic. E.g.: Razorback, AR08. If you have wide feet, this is your last. If you have normal or narrow feet, take half to a full size smaller or switch to a shoe with an ASHM last.
- ZD last = EEE width
Zero Drop last. Very wide fit, normal toe box height. Unstructured construction without reinforcement. All Barefoot Boots. If you have wide feet, this is your last. If you have normal or narrow feet, take half to a full size smaller or switch to a shoe with an ASHM last.
- STC last = EE width.
Steel Toe Cap last. Wide fit, high toe box. Originally developed for shoes with steel toe caps to create more space for the steel toe cap in the toe box, this last is now also used in other models without a steel toe cap. Like the JG last, but a touch narrower (EE width). If you have wide feet, this is also your last. If you have normal or narrow feet, take half to a full size smaller or switch to a shoe with an ASHM last.
- ASHM last = D width
Ashley Men last. Normal fit, normal toe box height. Toe cap reinforced with thermoplastic. E.g.: Numzaan, Schollie. Normal width last, higher instep. If you have normal or narrow feet, this is your last. If you have wide feet, take half to a full size larger or switch to a shoe with a JG, ZD or STC last.
Introducing the new “Chief” in the range – the Numzaan boot.
We are excited to introduce the Numzaan boot – crafted with the Jim Green touch for ultimate quality, comfort, and formality for any occasion.
Derived from the Zulu word “Numzaan” meaning “Head of a household” or “Leader”, we proudly present the Numzaan boot as the esteemed “Chief” in the Jim Green collection. Inspired by the Baobab boot, it provides a traditional feel and boasts the new vegetable-tanned leather, making it Jim Green’s most stylish boot yet.
- Material: Double layer vegetable-tanned leather (2.2mm full-grain leather, lined with 1.6mm calf leather)
- Water resistance: A double leather layer contributes to the water-resistance of the boot, if correctly greased, the boot is waterproof
- Toe Cap: Genuine leather toe cap with incorporated kiltie leather for added look and durability.
- Toe, heel, and eyelet area: Manufactured using a double layer of 2.2mm full-grain leather for added durability.
- Heel and toe stiffeners for added durability, support, and protection
- Steel shank between the insole and sole offers additional support and stability
- Leather lasting board, leather insole and a resin outsole for added comfort and durability.
- Heavy duty speed hooks and eyelets to secure your feet.
- Construction: Double stitched construction. The leather insole is attached to the upper with a double-stitched 2.2mm braided nylon cord.
- Resoleable: Like all Jim Green boots, these can be resoled indefinitely due to their construction
- Last: ASHM – Standard D width
- Sizing: Runs fairly big. If you are between sizes, go with the smaller size.
- Outsole: Frog Grip Sole
- Made in South Africa
The Numzaan boot boasts a double vamped upper (2.2mm lined with 1.2mm calf leather), which is then finished off with a genuine toe cap, resulting in this boot having over 5mm of leather on the toe. The heel and toe areas are also stiffened with thermoplastic toe puffs for added support. Added to this is an ankle high lacing system and a bellows tongue. The unique cutting pattern means less pressure on your laces when you need to tighten the boots a bit more. The ASHM last makes for a more ‘dressy’ look, whilst still fitting a wider foot. But the good news does not stop there, we have gone a step further and incorporated a leather lasting board, a leather insole and a resin outsole (over 8mm of leather in total), which will slowly mould to the shape of your feet. All of this is combined with the innovative Frog Grip sole or the Jim Green Lug sole.
