These gloves work with the Shark system on Leki poles. I was not enamored of the mesh version that comes with the poles, so I thought I would give these a whirl. I have TINY hands and sizing can be quite the challenge. I typically wear a men's small size in gloves. Based on the sizing chart and my hand measurements, this translated to a 7.0 on the Leki sizing chart.The gloves I received were clearly meant for elves. It was absolutely impossible to get my hands in them. So I returned them and ordered the next size up. (8.0). These are JUST big enough. I still have trouble getting them on over the width of my hand, but once in them, they are just long enough in the fingers to be workable. I am hoping they will stretch a bit as I wear them. Else I will be having to size up again.I am happy with the gloves overall, in terms of quality, performance, etc.. SO FAR. But if you buy these, think about sizing up at least one size. Better if you can try them on somewhere before buying. The run REALLY small.Oh, and use the sizing information on Leki's website. There were differences between the two charts.
