These are indeed really nice gloves, I'm very happy with them. Here are mine:
As for them running small, I have to say that my experience is that they run pretty much right where I'd expect them based on my usual fit for most clothing items and, actually, maybe even just a tad large based on careful adherence to the description of the measuring process. When I measured and measured twice I fell squarely into the suggested large ("L") size, despite my expectation and feeling that I ought to be a medium ("M"). When my gloves arrived they felt a bit on the big size; an exchange back to medium size confirmed my initial intuition and I have a much better fit. Frankly, given my short fingers, I'd probably best fit with small fingers on a medium hand sized glove. So, I think the lesson is to measure carefully, but allow that we all have unique dimensions and adjust accordingly.
I'll add that WW's customer service is outstanding - fast shipping, fast response to queries, and flexibility in making sure you get a product you're happy with. Az is good people - much recommended!
