Buying tip:This page is for riders choosing tall boots for lessons, shows or winter riding. Start with your calf and height, not your shoe size, because a boot that fits your foot but not your calf will not zip. Field boots suit hunters and jumpers, dress boots suit dressage, and a lined or waterproof boot covers winter.
What riders say about these tall boots
Riders tell us how these boots wear, warm and fit.
Horze Kids' Rover Tall Field Boots
★★★★★
These are my daughter's default riding boots. We've ordered them several times. Each time she outgrows them, we get them again! They last a full season of nearly daily wear and sometimes multiple horses a day.
★★★★★
Have been a blessing, had these in the past and they lasted about 5 years for everyday/lesson use. Tried to go with a different brand for about a year but ended up coming back to these. Super reliable and took about 5-6 rides to break in.
Equinavia Women's Ari Thinsulate Lace Country Boots
★★★★★
Worth every penny! Wyoming winters are no joke, and these boots keep me dry & warm. Didn’t need much “break in”. I ride in an English saddle, they fit well in stirrups.
These are fully fleece lined and very toasty -- perfect for winter riding. The velcro side straps make them very customizable in terms of calf width, which I appreciate since I have extra narrow calves, and the boots are tall enough to keep out drafts. The rubber bottoms are not clunky and are easy to hose off. The soft uppers don't offer firm ankle support, but that's about the only consideration I'd mention. I love them for cold weather trail riding.
Horze Women's Aspen Winter Tall Boots
★★★★★
Very comfortable out of the box. Not heavy like other brands. They look great too.
Horze Genve Teenage Tall Dress Boots
★★★★★
Having a thin young teen rider, we had trouble finding a tall dress boot that fit her leg. The teenage size fit her well and solved our problem. I’m so glad you carried this option.

Tall riding boots: which line is right for you
Pick by how you ride first, then by calf width. Tredstep Medici II, Sirani and Donatello III are the show-ring leather boots with the most calf and height options, Horze Rover, Duvall and Genève cover schooling and shows, and Equinavia Karolina, Karina and Kassi add leather and synthetic field and dress boots in three calf widths.
For winter, Horze Aspen, Utah and Polar, B Vertigo Cetus and Equinavia Ari are lined or waterproof. Horze Chester and Morgan are rubber and neoprene boots built for barn work and everyday riding, and they are easy to clean.
Equinavia is the sole US distributor of Horze, which is why Horze boots sit with Equinavia's own on this page (source: equinavia.com, Our Story, September 2025). Tredstep, a separate bootmaker, and B Vertigo are carried alongside them.
Tall boot sizing: calf, height and foot size
Measure two numbers before you order: the widest part of your calf and the height from the floor to the bend behind your knee, over the breeches and socks you ride in. Read both across the chart for your size and choose the calf width first.
Riders in reviews often mention calf fit, and boots from different brands fit differently, so go by the chart for the exact boot rather than your usual size. The charts below are the vendors' own, in the units each vendor uses.
Tredstep boots use their own charts for Medici II, Sirani, Donatello III and Donatello Junior S, with how-to-measure steps and calf and height by size.
See the Tredstep tall boots sizing guide for those charts.

Karolina (leather) and Karina (synthetic) field boots share one set of foot lengths and come in narrow (N), regular (R) and wide (W) calf. All numbers are inches; heights are for Karolina, and Karina runs 16.25 to 18 inches across the same sizes.

Tall boots FAQ
What size tall boots should I order?
Measure the widest part of your calf and the height from the floor to the bend behind your knee, over the socks and breeches you ride in. Then read both numbers across the size chart for the boot you want, because Equinavia lists US inches, Horze lists EU sizes and Tredstep has its own charts.
CloseWhat is the difference between field boots and dress boots?
Field boots have laces over the instep that give the ankle flex over fences, so hunters and jumpers usually choose them. Dress boots have a clean front for the dressage ring. Check your show's rulebook if you compete.
CloseAre Horze Rover boots real leather?
No. Horze describes the Rover as soft synthetic leather with a breathable mesh lining, and riders who review it say the same. It is a lower-maintenance boot for lessons and schooling.
CloseWhich tall boots are warm or waterproof for winter?
Horze Aspen has a faux fur lining, Horze Utah and Polar thermo boots are fully lined and fasten with hook-and-loop straps, and B Vertigo Cetus is waterproof with a Thinsulate lining. Equinavia Ari country boots add a waterproof membrane and Thinsulate insulation.
CloseDo these brands make tall boots for kids and teens?
Yes. Horze makes Rover kids' field boots, Chester kids' rubber boots and a Genève teenage dress boot, Equinavia makes the Kaia kids' field boot, and Tredstep makes the Donatello Junior S.
CloseWho are these tall boots for?
They suit riders who want tall boots from a family of boots we carry at every level: everyday rubber boots for the barn, field and dress boots for lessons and shows, and Tredstep leather boots for riders who need a precise calf and height fit. Riders who want custom-made boots will want to look elsewhere.
