I love the wide straps as they stay in my feet better. My previous rainbows were thin straps and it can feel a bit weird trying to keep them on while walking. Also, this is one of the few rainbows where you can send them in if a strap comes undone and/or "manufacture defects." I did with my previous ones and knew I needed another pair! I wear a 6.5 and the medium fits nicely! I didn't need to break them in, soft leather and comfort as soon as I tried them on! Get it, you won't regret doing so!
These rainbow sandals are a delight! They are a perfect fit, comfortable and love the chosen color. Walking is more pleasant becauae rhey are soft and have a bit of a lift for my 5"1 heigjt.
