Springy socks

Having been promising since before Christmas, I finally got around to making up some new socks for my daughter.  She has quite small feet but this pattern can be adjusted quite easily, although be sure to end up with an even number of stitches at the start of the leg as if you work odd you will end up with granite stitch!  (This pattern is for shoe size UK 6).   Based on cuff down socks I've made previously, this is what I came up with:

I used about half a 110g skein of colinette jitterbug in raspberry and a 3.5mm hook (written in American terms).
(Make 2!)
Cuff:
1.Ch6, sc in 2nd ch from hook and across, turn (5sc)
2-30: Ch1, sc back loop only across, turn.
sl st together to form the cuff by working in the back loops and underside bumps of the starting ch. Do not break yarn!
Leg:
1: working along the edge of the cuff, work (sc in 2 row ends, 2sc in next) around (40sc)
2-16: Without joining rounds, work sc, ch1, sk 1, sc around for 15 rows.  Work (sc, ch1, sk1 sc) twic more to bring last st level with cuff seam.
Heel:
1: sc in next 20, turn leaving remaining st unworked
2-8: ch1, sc across (20 sc)
9: ch1, sc in 1st st, sc2tog, (sc in next 2 st, sc2tog) across, sc in lst st, turn (15)
10: ch1, sc in first 2 st, (sc2tog, sc) across, sc in lst 2 st, turn (11)
11: ch1, sc in first st, (sc2tog, sc) across, sc in last 2 st, turn (8)
12: ch1, sc2tog across (4)
Do not turn or break yarn!
13: ch1, work 11 sc up the side, work in pattern across pattern section (should be 10 repeats of sc, ch1, sk1) 11sc down other side of heel.  Leave remaining sts unworked, do not turn!
14: (no ch 1 as sock is worked in a round from here: you may want to put a stitch marker in first stitch of the round and move it up on each new round) sc across the 4 unworked sts, sc in 9 sts along side of heel, sc2tog in last 2 on side, work in pattern across, sc2tog at top of next side, sc in next 9
3: 2sc2tog, sc along side, work in pattern, sc along other side
4: sc2tog, work in sc/patt/sc around (40)
Foot:
5-24: work in established pattern around (40)
Fold sock to find central stitch on the sole, work round to this point and mark as first stitch of round
Toe:
1: sc in next 8 (inc. first marked st), sc2tog, sc, sc2tog, sc in next 15, sc2tog, sc, sc2tog, sc in last 7 st (36)
2: sc around
3: sc in first 7 st, sc2tog, sc, sc2tog, sc in next 13, sc2tog, sc, sc2tog, sc in last 6 (32)
4: sc in first 6 st, sc2tog, sc, sc2tog, sc in next 11, sc2tog, sc, sc2tog, sc in last 5 (28)
5: sc in first 5 st, sc2tog, sc, sc2tog, sc in next 9, sc2tog, sc, sc2tog, sc in last 4 (24)
6-7: repeat pattern
8: sc in first 2 st, sc2tog, sc, sc2tog, sc in next 3, sc2tog, sc, sc2tog, sc in last 1, slst in first st of next round, fasten off with a long enough tail to sew toe.
