Fit: the two are super similar in width but the Tour is obviously taller, which I think has a more lengthening effect. For reference, I am ~5 feet tall and my calves measure about 12.5″ around at the widest point. Both are decently slim in the calves (I don’t expect a glove-like fit for functional rubber shoes), and one difference is the kids’ calf circumference at the widest point is the same as the leg opening, whereas the Tour tapers and gets a little slimmer at the opening which I like, since it mirrors how our calves narrow in right below the knees. Please note that as with all boots, shaft height and width likely increases as the foot size goes up.
Weight: My favorite aspect of the Tour by far though is the lightness – despite being several inches taller than the kids boots, the Tours are noticeably lighter. They are made of thinner rubber, and I do want to point out that they are excluded from Hunter’s typical 12 month warranty. That is a little disappointing, but I haven’t yet read any reviews of the Tour boots having quality issues (most negative reviews are usually due to the slim calf fit).
Style: Both have the classic boot shape with rubber ridged soles and decorative (not functional) buckle on the side. Both boots bend, but the Tour is more pliable since they’re designed to fold in half or roll up more easily. In my opinion though they are in no way flimsy and the soles are still durable in feel. The heel on the Tour is more defined in shape and marginally (maybe 1/4″) higher than the kids which I like. The kids actually looks pretty truncating on me in these photo against pale legs, but I promise they look more flattering with black tights or dark denim, like in this older pic:
Sizing: Hunters sizing is pretty straightforward, but when converted to kids metrics on American retailers it can get confusing. Both my kids and womens boots are labeled the same thing on the inside: “UK 3, US 4 male / 5 female, and EUR 35/36.” This tells me I’m consistently a UK 3 or EUR 35/36 whether I wear kids or adults. When ordering through US websites, though, I took a “5” in womens and a “4” in child or big kids sizing. Why the U.S. changes sizing for kids vs adults and then men vs womens beats me! Kids sizing goes up to a 6 child, which should equate to a sz EUR 37/38.
I usually wear a 5 or 5.5 in shoes, and the sizes I ordered leave me enough room for the fleece liner socks for warmth in the winter. The kids size Medium (4-6) fleece liner socks work for me in both – they just don’t fold over the top of the Tour which is fine with me. The fit is snugger with liner socks so I only wear these with tights or bare legs and not jeans.
Current retail: $80 for kids versus $150 for womens. Women’s tour is also sold at Zappos and Bloomingdales. Kids are also sold at Bloomies and Saks where available sizes differ.
Bottom line: Love the womens’ Tour if you’re looking for a tall and lightweight rubber boot with a slimmer calf fit (compared
to their originals). Since the Tour do hit right at the bottom of my knees, I would recommend the kids’ original for ladies who are shorter than myself (~5 feet tall) or have feet sizes smaller than an adult 5. For ladies with shorter legs and wider calves, perhaps try Hunter womens’ original short which run a little shorter and wider than the kids original.
