Many tourists record that women often walked bare-foot to market. There are several illustrations of this and some described how they carried their shoes from home to the outskirts of town where they put them on while selling their wares, and took them off again on their way home. The implication is that these were rural women: women who lived in towns probably wore shoes at all times.

It is not clear whether not wearing shoes was a matter of saving shoe leather or a preference for walking bare-footed  with a need to protect their feet from the filth and dangers of town streets, or that they felt they might sell more goods if they were properly shod.

Traherne illustrated women taking off their shoes on their way to or from market.

Shoes were presumably worn on Sundays and other special events with their best clothes.

It seems likely that walking in bare feet became much less common by the 1850s: there are no written references to the practice after that date, but a few illustrations, particularly R. Griffiths’ Welsh Fashions Taken on a Market-Day in Wales, of 1851 shows one woman with bare feet and footless stocking hooked over a toe. By this date railways had infiltrated much of Wales bringing in mass produced shoes and stockings. There was a change from a self-sufficient life-style to a money based one and the traditional costume becomes rarer. However, both men and women must have worn socks or stockings, and it is likely that most of these were knitted, but the evidence both in written accounts and illustrations becomes far rarer.

Welsh men were very rarely seen without shoes or stockings throughout the 18th and 19th centuries and their shoes were sometimes described as having buckles.

The Welsh language was not of ‘rational creatures’ and the Welsh are lazy and heathenish and had the itch. Most of the middle (and all the meaner) sort, are as absolute strangers to shoes and stockings, as to moral honesty.

1730 Cardigan
The maid at the Inn at Cardigan being dressed because it was Sunday, in the Evening put on her everyday clothes and laid by her shoes and stockings (waiting upon us as usual bare legged) only, I presume, to be worn on High days.

1755 Wales
The peasants wear no shoes about their houses, and in their common travelling the roads, they carry them in their hands, and wash their feet near the towns which they are travelling to, when they put on them and their stockings; many of them, however, have none. And yet these poor creatures would think themselves deemed to perpetual slavery if they were obliged to wear wooden shoes; the ideas of wooden shoes,  slavery, and French being all linked together in their imaginations; they would scarce prefer them to confinement without and as soon wear chains as preserve their feet from injury by these contrivances; the flattering idea of being free, though bare-footed, gives no little consolation amidst as much slavery as poverty and dependence can bequeath …

1769 Llanrwst
The inhabitants who are natives seem to be the real descendents of the Ancient Druids, both in shape and dress, numbers of both sexes which we saw, am pretty sure, never wore shoe or stocken [stockings] since they were created.
Anon, Bangor, UCNW, 3091, p. 9

1776 Machynlleth
Here and in most other towns in Wales I observed a piece of [?] of the women which is very unnecessary [?]. They either wear no stockings or have them made without feet and show their dirty toes.
Anon, (A Liverpool merchant), Tour in the Summer 1776, through Wales, NLW MS2862A, p. 42

Throughout the greater part of Monmouthshire and all Glamorganshire through which we travelled, most of the women and children, though in other respects comfortably dressed, wear no shoes or stockings,

Nicholson, Francis, The diary of Frances (Fanny) Nicholson, NLW MS15190C, entry for 19.8.1790

1791 Carmarthen
the common people despise the use of shoes and stockings. They consider these appendages as a useless piece of extravagance and I often met Welsh girls upon the road, who were dressed for a visit to their friends in a clean white petticoat tucked above the knee, trudging along the hard road, barefooted, with their shoes and stockings under their arms.

1791 Wales
‘It [bare feet] seemed to me to be a very humiliating and cruel mark of subjection; but this, Mr M — assured me, was not the case. It was, on the contrary, a sign that the women did not labour in the fields, as they do in England. {Men always wear shoes}
… Even the custom of walking bare foot does not proceed from the want of stockings, you see; nor has it such a disgusting appearance as persons unacquainted with it are apt to concede.
Morgan, Mary, Mrs, A Tour to Milford Haven, in the Year 1791, (London, 1795)

1793 north Wales
I find the fashion of wearing shoes and stockings, is more general here, than it was 30 years ago; when I have been frequently disgusted by the filthy appearance of the female waiters and chambermaids, having their bare feet clogged with mire and dirt.

1796 Swansea
The women and children in this country all go without shoes and stockings, a shocking nasty thing I think …

1798-1801 Wales
In the more unfrequented parts the women seldom wear any shoes, except on a Sunday, or the Market day, and even on those days they often carry them in their hands as they go along the roads. I have sometimes seen six or eight of them after their journeys from the adjacent villages, seated on the bank of a rivulet, in the act of washing their feet previously to their entering the towns.

The Welch girls of the lower order commonly go without shoes or stockings, but one would not expect to see a wench walking along a flinty road with her shoes in her hand. We could not but admire such economy.

1827 Neath
‘Today the Welsh lasses have thot [thought ?] proper to clothe their legs and feet. Yesterday in one walk from Merthyr we saw so much nakedness as quite to shock us.

1828 Aberystwyth
… the country people often go barefoot, indeed, shoes are rather an incumbrance in climbing hills and traversing rugged ground, black stockings are worn without feet but with a narrow slip passing over the upper part of the foot and bound by a loop round the second toe, there is a good reason for this, they have so much walking in bog land and their feet often wet with its yellow waters that stockings would be a great inconvenience.
