Fall is quickly approaching, which means that boot season is upon us. In Paris you see them everywhere with skirts, leggings, shorts, and jeans. Finding boots that fit full-size calves is a challenge, but as sizes grow and demand grows, they're becoming more widely available. More and more models are incorporating stretch panels and stretchy materials to give a better fit for large and/or muscular calves.
The key words you want to know when shopping for wide-calf boots are "gros mollet", "mollet fort", or "mollet large" (wide calf) and "extensible" (stretch). It's also helpful to know your "tour de mollet" (calf circumference)--in centimeters, of course. Also note that "bottes" refers to knee-high boots while "boots" and "bottines" are commonly used for calf-high and ankle-high models.
Boots that "s'enfilent" are those you pull on, while you zip up boots with a "fermeture éclair". Also, "grandes pointures" are longer sizes (generally 42-45, corresponding approximately to US sizes 10-1/2 through 12-1/2), while "grandes largeurs" are wide width. In France you usually don't have a choice of widths other than standard and wide, which is perhaps a B width at best and tends to be most often available in so-called comfort shoes that are not terribly stylish.
Obviously it's easiest if you can try them on before buying, but they can be hard to find in stores. Mail order is another option; be sure to check the exchange/return policy before ordering. A lot of mail order sites don't list the calf circumference, and pictures can be deceiving. Here's a list of places you can find wide-calf boots, but it doesn't hurt to also look around wherever shoes are sold--sometimes you get lucky.
