The short answer on What Causes Red Squiggly Lines in Eyes is below, and the honest version is that it depends on two or three things rather than one. A strap across the widest part of the foot is what stops slipping, not a tighter buckle. A moulded footbed takes about a week to break in and then lasts years. The groups below run from the decision that matters most to the ones you make afterwards.

What decides this is strap placement, footbed and heel height. Everything else is preference. Two from the first group show the range: Joseph's Anisa Patent Leather Slingback Shoes at $198, and Nobody's Child's Tan Chunky 70's Platform Heels at $68. The first is the considered buy; the second is the one to start with. A strap across the widest part of the foot is what stops slipping, not a tighter buckle. A moulded footbed takes about a week to break in and then lasts years. A higher price mostly buys materials and finishing, and occasionally it buys nothing at all.

A flat sandal reads dressier with a longer hem. From the second group, trinaturk.com's Naomi Slingback Heel ($90) is the one that earns its place, because it works in more than one context without being restyled. The third group is smaller and deliberately narrower, sandals, for the decisions you make after the main one. None of this needs the whole group. One piece from each is usually enough.

There are 20 pieces here from 12 brands, $44 to $486, all in stock when this was written. We would not buy all of them, and neither should you. nobodyschild.com's Khaki Suede Sandals at $44 is the low-risk way in, and PatBO's DALVA SANDAL at $486 only makes sense if this is a category you already use constantly. On what causes red squiggly lines in eyes specifically: the difference between the top and the bottom of this list is real but smaller than the price gap suggests. Nothing here is included because it is famous, and price is not used as a proxy for quality anywhere on this page. If you take one thing away: if you would not buy it at full price, you do not want it on sale.
