Overall, I love these and am considering purchasing in a different color or design. I liked the cushion on the sole and the open-airy feeling so that in the summer heat these are really comfortable. Liked the option for the variety 2pack with different sizes. I had to put 2 heel pads in for my little girl to wear them in a wedding because it was too late to get anymore. My preferences are light weight, comfortable, with a heel strike that has some padding. They are totally, and I mean totally, non-responsive. Or better still, spend a bit more and avoid any bike rack that uses rubber straps. Son perfectos c cómodos y de buena calidad, el precio es razonable, los comprare en otro color definitivamente I originally planned to send this printer to college with my kid, but now Im keeping this one at home and researching other options (so I dont have to get late-night tech support calls! I hope they sell this kind of eartip .
