I am now riding an XS Blue and am 5' 3" 3/4! I have size 6.5 feet. I know some people have complained about toe overlap on the Blue but I have not had an issue. My prior bike had a 26" front wheel to eliminate this problem. I think that any bike can have toe overlap and sometimes it can be unmanageable but a lot of times it's seen as more of an issue than it really is. We're typically leaning into a turn with our bodies, hopefully not doing too much steering with the wheel. I know there are some situations where this is necessary though. I've done hairpin turns on my Blue at nearly no speed..not a problem. So, a little toe overlap in my experience is not a big deal because it doesn't mean I'm actually hitting the tire.. but that's just been my experience.
