Choice of ugly sandals, or just give up?

[AgeingArtemis]

I should preface this first by saying that I am extremely unstylish and a bit butch, my standard summer clothes would be cargo shorts and a T-shirt. I also have extremely ugly and problem feet, so from experience the more stylish sandals look pretty awful and out of place on my feet. So in short, I am looking for the type on sandals your dad might wear.

In summer I usually wear flip flips (but get terrible blisters from the toe post, and there's not enough foot support) or trainers (but my feet get sweaty).

Given a choice between ugly walking sandals eg www.sportsdirect.com/karrimor-amazon-ladies-sandals-188030?colcode=18803003

or birkenstocks (not the cool ones....the geography teacher ones...)

Which do you think are least awful?

I already have the birkenstock (but can return them), I think they look ok with trousers but questionable with shorts. Walking sandals are usually even uglier, but perhaps more practical.

Maybe I should just give up and sweat in my converse for another year

I don't think there's any such thing as a flattering sandal. My feet look best covered up. The end.

This is one advantage of living in the north. On the rare days when boots or shoes won't cut it, I go for comfort and yes, a bit of fugliness. We can laugh all we like at the hipsters but I think they've called this one right.

I wear Teva Tirra sandals for summer they are very comfortable in fact I would recommend any Teva and they do have more urban styles. Also have you looked at birkenstock mayari?
