Tight fit, seams not durable - Columbia Summit Valley Legging - Women's

I usually wear a size small and purchased a size small. The leggings fit really tight on me, like compression fit. I'm not sure if the medium would be a better fit because I didn't get to try it on. My waist is 28". I don't like hiking in tight leggings but these would be great for running. The material isn't the most comfortable but it seems like it would resist pilling. The seams however are not durable. While taking off the leggings for the very first time, the stitching around the ankle hem burst. I'm glad I got this on sale, but it was still expensive for being so fragile.
