Update: As part of a Black Friday gear purchase, I picked up a pair of 2 XL Turtle Fins from Scuba Toys, with spring straps. Now, remember that my original issue is that my old Atomic Aquatics XL Smoke on the Water split fins were too tight when worn with my new SeaSoft Stealth 6 mm boots. Made my feet hurt.
2 XL Turtle Fins vs. XL Smoke on the Water splits.
This is what the Smokes look like on my feet (I normally wear a size 15 EE shoe):
Okay, here's now the new '2 XL' Turtle Fin (left) foot pocket compares to the XL Smoke (right). Not looking good...
Some measurements of foot pocket (TF on left, Smoke on right, neither vertical is true height, but rather top to bottom measured diagonally, but you can still get some idea of how it compares).
TF - ~ 3 1/2 inches top to bottom, diagonal, roughly 4 1/2 inches across? Looks like the Smoke is tad less wide, but a good deal taller.
So, how's the 2 XL Turtle Fin look on my foot?
Also, I new the Turtle Fins would be heavy, but wow! Smokes are, judging from an answer in the listing at Scuba.com, weight 4.4 lbs. OMS Slipstreams are roughly neutral, but the Turtles, Jets & Hollis F1s are heavy! I believe I saw a 7.5 lbs. figure for one pair of fins.
At TheDiveForum.com, Wilbo (with a familiar smoking chimp avatar) has a thread on The "What size should I buy?" thread - fins, from 2013, pertaining to fitting dry suit boots. It'll give us some comparisons. Some notes from him:
He measures the foot pocket opening of the Turtle 2 XL as just over 85 mm x around 95 mm, & of the Turtle 3 XL as around 80 mm (so it's shorter?!?!?) x 130 mm. He's got some photo comparison shots. TimmyG's post #2 comparison pic is really interesting.
DiveGearExpress has some foot pocket dimensions on OMS Slipstreams, but not the others. From their webpage on Slipstreams:

I've got an e-mail in to ScubaToys to find out about returning the Turtle Fins with spring straps, and to get some input as to my options. I don't think they carry the OMS Slipstream anymore, and I don't know if one would fit my foot or not.
I can't wrap my head around all this right now. Maybe tomorrow I can come back & re-read my own post & pull it together. Sheesh.

P.S.: Gotta wonder if for cold water boat diving I ought to just bite the bullet & buy some thin-soled 7 mm 'booties.' But would the 2 XL Turtles work then? At least the Smokes were comfortable enough diving 3 mm SeaSoft Sundays; maybe 7 mm booties would put me back in splits.

An old ScubaBoard thread Fins: OMS Slipstreams vs. Jets has a post by NWGratefulDiver; part of it states:
Michael
I've owned Jets, Turtles, Slipstreams and F1's ... I currently dive the F1's almost exclusively ... primarily because of the foot pockets.
The Slipstreams compare most closely to the Jets ... they're slightly stiffer and about half the weight. My biggest complaint with both is the foot pocket, which is more appropriate to a 2x6 than a human foot. And their sizes are just downright strange ... particularly for folks who wear drysuits. I think DIR went with Turbosoles mainly so they could fit into the little girlie foot pocket that both Jets and Slipstreams refer to as "XL" ... and if you go up one size to the XXL, you'd better have feet like an NBA basketball player.
Turtles used to be the alternative for folks in drysuits with normal size feet ... but their XXXL, which is all they came in before XS Scuba started producing them, is very wide. The Turtles are noticeably softer than either the Jets or Slipstreams, and although I generally like the fins they don't give you the "snap" on a good strong kick that you'll get with either of the other two.
F1's are my preferred fin because they give you both the desired performance and a foot pocket that's actually designed for normal people. I can wear this fin all day without discomfort ... and it gives you all the performance you'd ever want for both power and finesse kicking. The only downside to the F1's is that they're bloody heavy.
So for local diving I use the F1's exclusively. For travel, I have the Slipstreams ... which do work quite OK in a wetsuit bootie. I kept the Turtles around as loaners ... and I sold the Jets.
and in a later post:
I do like the stiffness of the Slipstream ... but for goodness sakes, couldn't they design the things to better accommodate a human foot?

Scubapro introduced the "New XXL" Jet last year and it nicely fills the gap between the XL and the old XXL, which is now the XXXL, (and I agree, you could fit a cantaloupe in the foot pocket). The new XXL fits my diminutive size-8-rockbooted-feet like it was made for me. One of my size-10/11 teammates tried it, since he was jamming his foot into a set of XL Jets when dry and was immediately sold. He had those "tweener" feet that wouldn't fit the old XL and the old XXL was ridiculous.
It's my understanding product may change over time, and some threads I turned up where several years old. See that mention of ScubaPro introducing 'the new XXL Jet?'
Old OMS Slipstream fins vs. Scubapro Jetfins thread from '07 on ScubaToys forum, CompuDude noted:
XL Jets and XL SlipStreams are nearly identical. The foot pocket on the SlipStreams is a smidge bigger... but a tiny smidge. Essentially the same fin, except one is heavy rubber that will last forever, and one is a lighter weight thermoplastic that may or may not last a long time (no long term tests to show yet, but they seem pretty rugged).
The foot pocket of XXL Slipstreams are not as large as XXL Jets (which are more like XXXXXL!). The downside is, if the XXL SlipStreams aren't big enough for you, you're SOL for SlipStreams, because there is no larger size.
In the water, the SlipStreams are a bit stiffer and I feel they provide a smidge less feedback as a result, but they are still very nice, and otherwise perform identically to Jetfins. If you like the extra weight on your feet from Jets (to avoid floaty feet in a drysuit, for instance, without needing the crutch of ankle weights), you may find your feet a bit too light with the SlipStreams. Conversely, if your feet are too heavy with Jets, the lighter SlipStreams may be a good option.
and
XL Jets and XL Slipstreams are nearly identically sized.
XXL Jets are friggin ginormous. Turtles are the in-between size.
I don't have Turtles, but I can tell you that XXL Slipstreams are about what you expect (incorrectly) XXL Jets to be sized... simply the next size up. So I'm guessing they're about the same size as Turtles.
The bad news, of course, is if you have really large feet and Turtles are too small, there is nothing analogous to the XXL Jets in a Slipstream fin, and you're SOL.
I've got an e-mail in to ScubaToys to find out about returning the Turtle Fins with spring straps, and to get some input as to my options. I don't think they carry the OMS Slipstream anymore, and I don't know if one would fit my foot or not.
