I've been looking into getting a pair of adidas Alphabounce, mainly for casual wear because I like their look and I've heard they're comfy. However, I noticed there are few different versions; I am aware of 5: Original (tight stiff mesh), CK (circular-knit mesh), EM (engineered mesh), RC (lighter version?) and Beyond (designed for cross-training). I was able to find the CK and RC in my size for around $40. I'm leaning toward the CK right now because I like the colorways better, but for those of you who have tried the Alphabounce before, feel free to give some advice.
